Question

the total surface area of a cube is 216 cm^2. find its volume

Answer 1

Tsa of cube =6a^2

216=6*a^2

216/6=a^2

36=a^2

6^2 =a^2

a=6

Volume of cube=a^3

=6^3

=216 cm^3...

Ans ---- 216 cm^3

Answer 2

total surface area of cube:-$6l^2$

$216^2=6l^2$

$l^2=\frac{216}{6}$

$l^2=36$

$l=6cm$

volume of cube:-

$Side*side*side$

$6*6*6$

$216 cm^2$
