Question

Find the cost of digging a cuboidal out 8m long 6m broad and 3m deep at the rate of rs 30per meter cube?​

Answer 1

Given

Lenght of the cuboidal = 8m

Breath of the cuboidal = 6m

Height of the cuboidal = 3m

Formula-:

$\bold{Volume \: of \: the \: cuboidal} \\ \bold{= length \times breath \times height}$

Now-:

On putting the required values

We get,

$= > Volume = 8 \times 6 \times 3 \\ = > \boxed{Volume = 144 {m}^{3} }$

Now-:

As given the rate of digging is

1 m cube = 30 /-

144 m cube = 30 x 144

= 4320/-

Therefore-:

Total cost will be rupees 4320.

Answer 2

Answer:

volume of cubiod = l×b×h

volume. =8m×6m×3m

volume =144m^3

rate of 1 m^3 = ₹30

for 144m^3 cost will be = 144×30 = ₹4320

Total cost will be ₹ 4320
