Question

The dimensions of a cuboid are in the ratio 5:2:1. Its volume is 1250 cubic metres. What is its
total surface area?

Answer 1

Answer:

Given that the length,breadth and height are in the ration 5:2:1

Let us assume the dimensions to be as l=5x b=2x and h=x

lbh=volume

5x*2x*x =1250

10x³ =1250

x³ =125

x=5m

l=5*5=25m

b=5*2=10m

h=5m

surface area of a cuboid : 2(lb+bh+hl)

2(25*10+10*5+25*5)

2(250+50+125)

2(425)=850m²

Surface area of cuboid=850m²
