Question

total surface area of a cube us 216 m*2 find volume

Answer 1

TSA of cube = 6(a)^2
216 m^2 = 6a^2
a^2 =216/6
a^2 = 36 m
a = √36
a = 6 m
Volume of cube = a^3
= (6)^3
= 216 m^3

Answer 2

Hey!

____________________

TSA of cube = 6× side^2
TSA of cube as given= 216 m^2

Side =?

216= 6 × side^2
216/6= side^2
36= side^2
Side = √36
Side = 6 m

Volume of cube= Side^3
Volume = 6×6×6
Volume= 216 m^3
