Question

The total surface of a cube is 9 3/8 cm2. Find the side of the cube.

Answer 1

Answer:

7.5 cm

Step-by-step explanation:

Total Surface Area of cube = 6$l^{2}$ where l is the side of the cube. In our example we have surface area provided, So we have to back track to get the length of the side.

9 $\frac{3}{8}$ = 6$l^{2}$

(75 x 6)/ 8 = $l^{2}$

$l^{2}$ =56.25

l = 7.5 cm

So the side of the cube = 7.5 cm
