Question

ratio of the volume and lateral surface area of a cuboid is 152:35 and total surface area is 1378cm² find its height​

Answer 1

Answer:

is given that length =24 cm, breadth 25 cm=0.25m and height =6m

Lateral surface area of a cuboid =2×24.25×6

By multiplication

Lateral surface area of a cuboid =291 m

2

We know that

Total surface area of cuboid =2(Ib+bh+Ih)

By substituting the value

Total surface area of cuboid =2(24×0.25+0.25×6+24×6)

On further calculation

Total surface area of cuboid =2(6+1.5+144)

So we get

Total surface area of cuboid =2×151.5
