Question

the square room has volume 500 m cube if the cost of painting its four walls at Rs 8 per metre square be rupees 1600 find the height of the room​

Answer 1

Answer:

2.5 m

Step-by-step explanation:

Given the square room has volume 500 m cube if the cost of painting its four walls at Rs 8 per metre square be rupees 1600 find the height of the room

cost of painting four walls is Rs 1600

For 1 sq mtr painting is Rs 8

So for 4 walls to be painted = 1600/8 = 200 m^2

Volume of room = volume of walls

500 m^3 = a x h

500 = 200 x h

h = 500/200 = 5/2

h = 2.5 m
