Question

find the volume and the surface area of a cube whose its measures 7 cm​

Answer 1

Answer:

Volume of cube=side cu

Volume=7×7×7

=343cm cu

Surface area of cube=6×a sq

Surface area= 6×7×7

=294cm sq

Answer 2

Answer:

Volume= 343 cm^3 and surface area =294 cm^2

Step-by-step explanation:

Volume of cube is given by the formula (length)^3

V= l^3

V= (7)^3

V=343 cm^3

Surface area is the area of all the sides

Area of one side = L^2

There are 6 surface so total surface area is 6 times the surface area of one side.

Area = 6 × (7)^2

= 6 × 49

= 294 cm^2
