Question

tsa of a cube is 384 find its volume

Answer 1

TSA of cube = 6(a)^2
384 = 6(a)^2
a^2 = 384/6
a^2 = 64
a = √64
a = 8 cm
Volume of cube = a^3
= 8^3
= 512 cm^3

Answer 2

hii!!

here's ur answer...

let the side of the cube be a.

given TSA of the cube is 384cm²

therefore 6a²=384cm²

→a²=384/6

→a²=64cm

→a=√64

→a=8cm

thus the side of the cube is 8cm.

verification:-

TSA of the cube=6a²

=6×8²

=6×64

=384cm²

hence verified

volume of the cube=side³

=8×8×8

=64×8

=512cm³

hope this helps u..!
