Question

The total surface area of a cube is 726cm.Find its volume

Answer 1

Answer:

Let, each side of the cube is a units

Given,

surface area = 726 cm²

or, 6a² = 726

or, a² = 121

or, a² = 11²

or, a = 11

∴ a = 11 cm

Now, volume of the cube

= a³ cm³

= 11³ cm³

= 1331 cm³

Answer 2

total surface area of cube = 6l²

726cm = 6l²

l²= 726/ 6

l²= 121

l = square root 121

l = 11

therefore,

volume of cube = side³

= 11³

= 1331cm
