Exercise 37 Page 336

Remember the formula for the surface area of a cube.

294yd^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= 7 into the formula to calculate S.

S=6s^2

s= 7

S=6( 7)^2

Calculate power

S=6(49)

Multiply

S=294

The surface area of the cube is 294 square yards.
