a can of soup has a diameter of 6cm and height of 9cm. How much soup will the can hold (use 3.14) round to the nearest hundredth
Answers
Answer:
V = Π (4)2*12
V = 603.19 cm3
Step-by-step explanation:
A soup can is a cylinder.
The formula for volume of a cylinder is the following: V= Πr2h.
We are given the height which is 12 (h=12) and the diameter which is 8 (d=8).
The formula asks for radius so we divide the diameter by 2.
r =8/2 = 4.
Now we can just plug the numbers into the formula
V = Π (4)2*12
V = 603.19 cm3
Since the units of measure are in centimeters, the volume will be measured in cubic centimeters.
V = 603.19 cm3, A soup can is a cylinder.
The formula for volume of a cylinder is the following: V= Πr2h.
We are given the height which is 12 (h=12) and the diameter which is 8 (d=8).

r =8/2 = 4.
Now we can just plug the numbers into the formula

1. Find the perimeter of the base of the treasure chest in feet
2. Find the area of the base of the treasure chest in square feet.
3. Can you use the expression from part c in exercise (#3) to find the surface area of the treasure chest in exercise 2? Explain
4. One cubic inch of sand weighs about 1 ounce. Find the weight of the treasure chest (in pounds) after it is filled with sand. Assume that the chest weighs 20 pounds when empty.
*There are 16 ounces in a pound
Answers
Answer:
2. 7
4. 60
Step-by-step explanation:
Because most chests are rectangles, we can assume that the base is also a rectangle
This means that the perimeter would be 3+3+2+2, which is 10 ft
2.
To find the area of the chest’s base, you must multiply 3 by 2
3*2 is 6, so the answer is 6 feet squared
3.
I’m not completely sure what this question is asking, but I’ll do my best
It looks like it is asking if you can find the surface area by multiplying the base by one of the side lengths (again, not sure which one because it’s not labeled)
This wouldn’t work regardless of the side length, however, because base times height is equal to the volume of the chest and not the surface area
4. To do this, it would be easier to find how much sand can fit in the chest, and then do weight after you have that figure
There are 12 inches in a foot, so the measurements of how much sand can fit in the chest could be found by multiplying 12 by the side length
This would leave you with measurements of 36, 24 and 24
Volume is base * height, so first multiply the two base measurements (36 and 24)
This leaves you with 624
Multiply that by height (24) and you get 14,976 cubic inches of sand
Because each cubic inch of sand weighs about 1 ounce, we know that the weight of the sand is 14,976 ounces
To find out how much that is in pounds, divide 14,976 by 16
This leaves you with 936 lbs
Add the additional 20 that comes from the chest and you get 956 lbs total
The chest weighs 956 pounds when filled with sand
Hope that helped!

How many cubes that measure 2 inches by 2 inches by 2 inches would fit inside a cube that measures 10 inches by 10 inches by 10 inches? Justify.
Answers
The number of the small cube that fits inside the larger cube is 125.
Given to us,
Side of small cube, s = 2 inches,
Side of larger Cube. S = 10 inches,
We know that volume of a cube is given by a³, where "a" is the side of the cube.
Volume of the small cube = s³ = 2³ = 8 in.³
Volume of the Larger cube = S³ = 10³ = 1000 in.³
The number of the small cube that fits inside the larger cube
[tex]\bold{=\dfrac{Volume\ of\ the\ Larger\ cube}{Volume\ of\ the\ small\ cube} }[/tex]
[tex]\bold{=\dfrac{1000}{8} = 125 }[/tex]
Hence, the number of the small cube that fits inside the larger cube is 125.

Answer:
A.
Step-by-step explanation:
The volume of rectangular prism is l x w x h
So, 12 x 6 x 8 =576
Volume of triangular prism is l x w /2 x h
So, 6x8=48/2= 24
24x12=288
576/288=2
This shows that the rectangular prism is 2 times larger than the triangular prism.
Therefore, the answer is A.
