The length of a room is 2 times it's breadth and 5 times of it's height.If the volume of the room is 800 m cube find the cost of papering it's wall at rs 6 per m²
Answer:
Rs. 1440
Step-by-step explanation:
Given that:
Breadth = b
Length = 2b
Height = 2b/5
Volume = b * 2b * 2b/5
Volume = 800 m³
800 = b * 2b * 2b/5
800 * 5 = 4b³
4000 = 4b³
4000/4 = 4b³/4
1000 = b³
10³ = b³
b = 10m
Length = 2 * 10 = 20m
Height = (2 * 10) / 5 = 4m
If plastering is at Rs. 6 per m²
Surface area:
2(lenght + breadth) height
2(20 + 10)4
2(30)4 = 240m²
Rs. 6 * 240 = Rs. 1440
