Question

of 0.25 paise/cm?
The length, breadth and height of a tank are in the ratio of 4:3:2. The tank can hold
3000 L of water. If the tank is open, what is the cost of painting the tank at the rate​

Answer 1

Answer:

Let the length(L), breadth(B) and height(H) be 4p, 3p and 2p.

Then volume = 4p×3p×2p = 24p^3 =3000

p^3= 3000/24 = 125

p=5

L =4p = 20, B=15, H= 10

Surface area of the open tank=2× (L×B + B×H + H×L) -(L×B)

In this put values of L,B,H

=1000

Cosy of painting= 0.25×1000= 250 Rs
