Question 4
Find the cost of digging a cuboidal pit 8 m long, 6 m broad and 3 m deep at the rate of $Rs30per{m}^3$.

Answer 1

The given cuboidal pit has its length (l) as 8 m, width (b) as 6 m, and depth (h) as 3 m.

$Volumeofthepit=l\times b\times h=(8\times 6\times 3)m^3=144m^3$

Cost of digging per $m^3$ volume = Rs. 30

Cost of digging $144m^3$ volume = $Rs.(144\times 30)$ = Rs. 4320
