Question

A hall is in the form of a cuboid of edges 15m,10m and 8m.find the area of flat roof​

Answer 1

Answer:

Area of the flat roof = 150 m²

Step-by-step explanation:

Hall is in the form of cuboid, with edges 15m, 10m, 8m

Thus, the base dimensions are

Length of the hall L = 15 m

Width of the hall W = 10 m

Height of the hall H = 8m

To find : Area of the flat roof.

As the roof is flat, the dimensions of the roof will be same as the dimensions of the base of the hall.

i.e., Roofs length = L

& Roofs width = W

∴ Area of the Roof = L × W

∴ Area of the roof = 15 × 10

∴ Area of the roof = 150 m²

Answer 2

answer : 150 m²

explanation : given,

length of cuboid hall, L = 15m

breadth of cuboid hall, B = 10m

height of cuboid hall, H = 8m

we know, area of flat roof = area of rectangle of side length L and B

we know, area of rectangle = length × breadth

so, area of flat roof = 15 × 10 m²

so, area of flat roof = 150 m²
