The dimensions of a room are 8m * 6m * 3m. It has one door with the size of 1.5m*1m. Find the cost to paint the walls if it costs ₹10 per square m.

Answer 1

Answer:

₹1025

Step-by-step explanation:

given

dimensions = 8×6×3

door =1.5×1

area of wall = csa - ar(door)

=2( lh + bh ) - 1.5

=2( 8*3 + 6*3 ) - 1.5

=2*3(8+6) - 1.5

=6×14 - 1.5

=104 - 1.5 = 102.5cm^2

cost of painting = 102.5 × 10 = ₹1025
