Question

if TSA of cube is 54 cm. what is it side​

Answer 1

TSA of Cube = 6a^2

Given,

TSA of Cube = 54 cm^2

This implies:

TSA of Cube = 6a^2

54 = 6(a^2)

a^2 = 54/6

a^2 = 9

a = √9

a = 3

Hence, the side of the cube whose TSA is 54 cm^2 is 3 cm.

TSA = 6× side^2

$54 = 6 \times side {}^{2}$

$side {}^{2} = 54 \div 6$

$side = \sqrt{9}$

$side = 3cm$
