Answer 2

Given - Internal measurement of room = 10 metre*7 metre* 4 metre.

Find - Area of four walls to be painted.

Solution - Lateral surface area of the cuboid will represent the area of four walls of them room. The formula for lateral surface area of cuboid is 2 (length + breadth) *height.

As per the question states, length will be 10 metre, breadth will be 7 metre and height will be 4 metre.

Keeping the values in equation-

Area to be painted = 2 (10+7)*4

Area to be painted = 136 metre².

Thus, Rohan wants to paint area 136 m².
