# Find the cost of digging a cuboidal pit 8 m long, 6 m broad and 3 m deep at the rate of ` 30 per $${m}^{3}$$.

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

We know that,

Volume Of pit
= (8 x 6 x 3) $${m}^{3}$$ = 144 $${m}^{3}$$

Now, Cost of digging per $${m}^{3}$$ volume = Rs. 30

$$\therefore$$ Cost of digging 144 $${m}^{3}$$ volume
= Rs. (144 x 30) = Rs. 4320
