Question

find the cost of digging a cuboidal pit 8 m long , 6 m broad,and 3 m deep at the rate of RS 30 per m^3.​

Answer 1

Answer:

length=8m

breadth= 6m

height=3m

volume of Cuboid= l×b×h

8m×6m×3m

=144m^3

cost= 144×30

RS 4320

Answer 2

Step-by-step explanation:

Length of cuboidal pit (l) = 8 m

Breadth (b) = 6 m

Depth (h) = 3 m

Volume of cuboidal pit , V = l × b × h

V = 8 × 6 × 3

V = 144 m³

Volume of cuboidal pit = 144 m³

 

Cost of digging 1 m³ = ₹ 30

Cost of digging 144 m³ cuboidal pit = 30 × 144 = ₹ 4320

Hence, cost of digging a cuboidal pit is ₹ 4320.
