Answer:

Step-by-step explanation:

1. Given the length, width and tallness discover the volume, surface region and inclining of a rectangular crystal  

h, l and w are known; discover V, S and d  

V = lwh  

S = 2(lw + lh + wh)  

d = √(l2 + w2 + h2)  

2. Given the surface region, length and width discover the tallness, volume and askew of a rectangular crystal  

S, l and w are known; discover h, V and d  

h = (S - 2lw)/(2l + 2w)  

V = lwh  

d = √(l2 + w2 + h2)  

3. Given the volume, length and width discover the stature, surface territory, and slanting of a rectangular crystal  

V, l and w are known; discover h, S and d  

h = V/lw  

S = 2(lw + lh + wh)  

d = √(l2 + w2 + h2)  

4. Given the inclining, length and width discover the tallness, volume and surface space of a rectangular crystal  

d, l and w are known; discover h, V and S  

h = √(d2 - l2 - w2)  

V = lwh  

S = 2(lw + lh + wh)

Sarah is finding the surface area of a cube. Find the surface area of the cube with dimensions of 8 cm each



Answers

Surface area of cube = 6a2
= 6x8x8
= 6x64
= 384 cm2

Hope this helps
Please mark brainliest

Answer:

384 cm^2

Step-by-step explanation:

A = 6a^2    (a = side length)

A = 6(8^2)

A = 6(64)

A = 384 cm^2

More explain stuff:

a^2 is what is used to find the area of a 2 dimensional square. You can also use a · a. Remember, a = side length. Since there are 6 sides/faces in a cube, you multiply the area of each face by 6. :D

6m - 8 = 1/2(-4m + 16)

Answers

Answer:

m=2

Step-by-step explanation:

6m - 8 = 1/2(-4m + 16)

Distribute

6m -8 = -2m +8

Add 2m to each side

6m-8+2m = -2m +8+2m

8m -8 = 8

Add 8 to each side

8m-8+8 = 8+8

8m = 16

Divide each side by 8

8m/8 = 16/8

m=2
