Question

the parameter of one face of cube is 20 cm find the total area of six faces the and the volume of the cube​

Answer 1

Answer:

In a cube all sides are equal.

Given perimeter=20cm

It means

4a = 20cm

a = 20/4cm

a = 5cm

Now total area of a cube = Area of one side × 6

= 6a²

=6×5²

=150cm²

And a volume

= a³

= 5³

= 125cm³
