Do as directed
8 If the length of a cube is 2 cm then find the surface area of the cube?
9. The length of cuboid is 6 cm. width 3 cm and height 1 cm, then find the volume of
cuboid
10. If the radius of a cylinder is 14 cm and the height is 5 cm, then find the volume of
this cylinder. (=​

Answer 1

Answer:

8. 18 cm^2 9. 18cm^3 10. 3080 cm^3

Step-by-step explanation:

8. Length = 2cm

Total surface area = 6a

n b b = 6× 2

=18cm^2

9. Length = 6cm , Breadth = 3cm , Height = 1cm

Volume = l×b×h

= 6 × 3 × 1

= 18cm^3

10. Radius = 14cm

Height = 5cm

Volume =

$\pi {r}^{2} \times h$

22/7 × 14× 14× 5 = 44 × 14 × 5

so, volume = 3080 cm^3
