Question

The total surface area of a cube is 54 cm square . Find the side of the cube

Answer 1

Answer:

The side is 3 cm

Step-by-step explanation:

The formula to find the TSA of a cube is 6$a^{2}$, or simply just 6 x a x a, where a is the side.

Given- TSA=54 cm square

=>6$a^{2}$=54

=>$a^{2}$=54/6   (Transposing)

=>$a^{2}$=9

=>a=$\sqrt{9}$       (transposing)

=>a=3

Answer 2

Answer:

total surface area is 54 cm

6a ^2 = 54 cm

a^2 = 54 / 6

a^2 = 9

a = 3

side of the cube is 3 cm
