Question

find the volume of a cube if its total surface area is 294 sq cm ​

Answer 1

Answer:

volume of cube = 343 cm³

Step-by-step explanation:

given

total surface area is 294 sq cm ​

total surface area of cube = 6 ( side )²

294 = 6 × side²

294/6 = side²

49 = side²

side = 7 cm

now volume of cube = side³

volume of cube = 7³ = 343 cm³

Answer 2

Surface area of the cube = 294cm²

6(l)² = 294 cm²

l² = 294/6

l = √49

L = 7cm

There the edge of the cube is 7cm.

The volume of the cube = l³

= (7)³

= 343cm³

Therefore, the volume of the cube is 343cm³.
