Question

Calculate the cost of panelling
the four walls of a room, whose dimensions are 3.8 m x 4.5 m x
35 m at the rate of 285 per square metre.​

Answer 1

Answer:

Step-by-step explanation:

Lateral surface area of cuboid=2x(bh+lh)

=2x(3.8x4.5+35x4.5)

=2x(17.1+157.5)

=2x(174.6)

=332.1.

BUT,the cost is 285 per sq. m.

total cost=285x332.1

=74722.5

!the total cost is 74722.5(much costly though!)
