Question

Find the area of 4 walls of a room whose length is 10m, breadth is 8m and height is 6m.

Hence find the cost of painting the walls if the cost of painting is Rs 25 per sq. m.

Also find the volume of the room.​

Answer 1

Step-by-step explanation:

Curved surface area=2h(l+b)

=2*6(10+6)

=12(16)

=192sq.m

Cost of painting =192*25

=4800Rs

Answer 2

Answer: Cost= ₹5400

Volume= 480m³

Step-by-step explanation:

Lenght(L)= 10m

Breadth(B)= 8m

Height(H)= 6m

Area of all the four walls=2(L×H)+2(B×H)

=216m²

Therefore the cost of painting all the four walls= 216×25 =₹5400

Volume of the room= L×B×H =10×8×6=480m³

Thank you.
