Question

The dimensions of a cuboid are in the ratio of 3:2:1 and the lateral surface area of the cuboid is 200m^2. The outer surface area of the cuboid is painted with enamel @ of rupees 10 per m^2. Find the total cost of painting the outer surface of the cuboid

Answer 1

Answer:

heyyy,

:let the dimensions of cuboid be x.

Then, length=3x

Breadth=2x

Height=2x

A/q

2(l+b)h=200

2×(3x+2x)2x=200

20x=200

X=200÷20=10

Now,

Length=3x=3×10=30m

Breadth=2x=2×10=20m

Height=2x=2×10=20m

T.s.a of cuboid=2(30×20+20×20+20×30)

=3200m2

Cost=10×3200=₹32000ans
