Question

The number of planks of dimensions 4 m x 0.50 m x 20 m that can be stored in a pit which is
40m long, 12 m wide and 160 m deep is

a)1900
b)1800
c)1920
d)1840​

Answer 1

Step-by-step explanation:

Calculate the volume of planks & pit.

Volume of planks = l × b × h

= ${4m\:×0.50m\:×20m}$

= 40 m³

Volume of the pit = l × b × h

= ${40m\:×\:12m×\:160m}$

= 76,800 m³

No. of tiles = $\Large{\frac{ v.\:of\:pit}{v.\:of\:plank}}$

= $\Large{\frac{76,800}{40}}$

= $\large{\boxed{1920}}$
