Answer 1

8*4*20*25 =
Rs. 16000

Answer 2

Answer:

The cost of the wall is Rs.160.

Step-by-step explanation:

Given : A wall 8m long,4m height and 20cm thick and the rate of Rs.25 per m.

To find : The cost of the wall?

Solution :

Length of wall = 8 m

Breadth of wall = 20 cm = 0.2 m

Height of wall = 4 m

Volume of the wall is

$V=l\times b\times h$

$V=8\times 0.20\times 4$

$V=6.4m^3$

Rate is Rs.25 per meter.

So, Cost of the wall is              

$C=6.4\times 25$

$C=Rs.160$

Therefore, The cost of the wall is Rs.160.
