Exercise 38 Page 336

Remember the formula for the surface area of a cube.

8672mi^2 or 433 12mi^2

Practice makes perfect

We want o calculate the surface area of a cube. Let's see the given measurements on the cube.

To calculate the surface area of a cube, we can use the following formula. S=6 s^2 The letter s represents the length of the edge of the cube. Then s^2 is its area. It is multiplied by 6 because all the faces of a cube are squares with the same dimensions. Let's substitute s= 8 12 into the formula to calculate S.

S=6s^2

Substitute

s= 8 12

S=6( 8 12)^2

a bc=a* c+b/c

S=6(8* 2+1/2)^2

Multiply

S=6(16+1/2)^2
