Answer 2

Before, finding the answer. Let's find out we can find the answer.

• Here, in this question, we are asked to find the Surface Area of the Cuboid.
• So, to find the surface area of the cuboid box, we must use the formula of :

$\boxed{ \tt Surface \: Area = 2lb+2lh+2hb }$

__________________________

Given :

• Length = 4 cm
• Breadth = 7 cm
• Height = 10 cm

To find :

• surface area of the box

Solution :

Surface Area = 2lb+2lh+2hb

                      = 2(4 × 7) + 2(4 × 10) + 2(10 × 7)

                      = 2 (28) + 2 (40) + 2 (70)

                      = 56 + 80 + 140

                      = 276

Therefore, Surface Area of the Box is 276 cm².
