Question

find the surface area and volume of a cube whose one length is 7 cm

Answer 1

Surface area = 6a² = 6*(7)² = 294 cm²
And, Volume = (7)³ = 343 cm³

Answer 2

Hi ,

Side of a cube ( a ) = 7cm

1 ) Total surface area = 6a²

A = 6 × 7²

A = 6 × 49

A = 294 cm²

2 ) volume ( v ) = a³

= 7³

= 343 cubic cm

I hope this helps you.
