(a) The volume of a cube of side 1 cm is equal to …..m³
(b) The surface area of a solid cylinder of radius 2.0 cm and height 10.0 cm is equal to…(mm)²

Answer:

(a) Expression for volume of cube is V = a³ ,

Here, a = 1cm

Therefore, V = (1 cm)³ = (10^-2 m)³ 

V = 10^-6 m³.

(b) Expression for surface area of a solid cylinder = curved area + area on top /base

= 2πrh + 2πr² 

Surface area of a solid cylinder = 2πr (h + r)

Given, r = 2 cm = 20 mm and h = 10 cm = 100 mm

Putting values => Surface area = 2πr (h + r) = 2 x 3.14 x 20 (100 + 20)

Surface Area = 15072  mm²

Hence, the answer is 15072 mm².
