Question

Net of cuboid having lengh, breadth and height 5,4 and 3 find the area of all faces

Answer 1

The area of all faces of the cuboid is 94 square units

Explanation:

Given:

Length = 5

Breadth = 4

Height = 3

To Find :

The area of all faces = ?

Solution:

The area of all the faces = surface area of the cuboid

The surface area of the cuboid = 2(LB + BH + HL)

where

L is the length

B is the breadth

H is the height

Now substituting the values,

The surface area of the cuboid

=>
`2(5 * 4 + 4* 3 + 3* 5)`

=>
`2(20 + 12+ 15)`

=>
`2(47)`

=>94 square units
