Question

find the volume of a cube whose surface area is 294 cm

Answer 1

Surface area of cube = 6L^2
WHERE L REPRESENT THE SIDE OF CUBE
SO, 6L^2 = 294
L^2 =294/6
l^2 =49
l=_/49
l= 7cm
volume of cube = l^3
=7^3
=343cm^2
HOPE IT HELPS! !

Answer 2

Hey mate.
=======

Given, The surface area of a cube is 294 cm^2

We Know,

The surface area of a cube = 6 (side)^2

=> 294 = 6 ( side ) ^2

=> 294 / 6 = (side) ^2

=> 49 = (side)^2

=> 7 = Side

Thus,

Volume of a cube = (side)^3

= (7)^3

= 343 cm^3

Hope it helps !!
