Question

find the lateral surface area of cuboid whose Length breadth and height are 8 cm 7 cm and 4 cm respectively

Answer 1

Answer:

Given,

Length of cuboid=8cm

Breadth of cuboid=7cm

Height of cuboid=4cm

A/Q

L.S.A of cuboid =2(l+b)×h

                         =2(8+7)×4 cm²

                         =2×15×4 cm²

                         =30×4 cm²

                         =120 cm² ANS.

Step-by-step explanation:

Answer 2

Given:

• The length of the cuboid = 8 cm
• The breadth of the cuboid = 7 cm
• The height of the cuboid = 4 cm

To Find:

• The lateral surface area of the cuboid.

Solution:

The formula to find the lateral surface area of the cuboid is given by,

LSA = 2*(l+b)*h → {equation 1}

Where "l" is the length, "b" is the breadth, and "h" is the height.

On substituting the given values in equation 1 we get,

⇒ LSA = 2*(8+7)*4 {adding the terms in bracket}

⇒ LSA = 2*15*4 {multiplying the terms}

⇒ LSA = 120 $cm^2$

∴ The lateral surface area of the cuboid = 120 $cm^2$.
