prisim a and prisim b have the same volume. which could be the dimensions of prisim b?​

Answers

Answer:

length = 4 feet

width = 4 feet

height = 10 feet

Step-by-step explanation:

8x4x5 = 160

4x4x10 = 160

Answer:

length = 4 feet

width = 4 feet

height = 10 feet

Step-by-step explanation:

First we must find the volume of prism A

Assuming that the prism is a rectangular prism we can easily calculate the volume by multiplying the length by the width by the height

So V = 8 * 4 * 5

8 * 4 = 32

32 * 5 = 160

Hence, the volume of prism a is 160ft²

The question states that the volume of prism A is  the same as the volume of prism B. Given that information we want to find the possible dimensions of prism B such that volume of prism A = volume of prism B.

We can do this by find the volume of each answer choice ( again, assuming that their rectangular prism )

For the first answer choice

4 * 4 * 10 = 160

160 = 160 however lets check the other answer choices.

For the second answer choice:

5 * 4 * 7 = 140

140≠160 therefore the second answer choice is not correct

For the third answer choice

8 * 4 * 6 = 192

192 ≠ 160 therefore the third answer choice is not correct

For the fourth answer choice

I can't see the dimensions, however we already know that the answer is the first answer choice.

Step-by-step explanation:

so I don’t know how many numbers there are on this cube (a standard number cube has #1-6) but I’m going to go with 10 numbers (don’t know how this is possible but anyway-). I’ll edit my answer if needed.

10 numbers

10 (numbers) - 2 (#8 and #10) = 8 (possible numbers)

so 8/10 or 80%

reduced fraction: 4/5

percentage: 80%

fraction: 8/10
