Question

Find the surface area of cuboid with length 8 cm breath 6 cm and height 7 cm

Answer 1

Answer:

SA of cuboid = 2(LB+BH+HL)

Given :

Length = 8cm

Breadth = 6cm

Height= 7cm

== 2(48+42+56)cm²

= 292cm²

Answer 2

Given: The length of the cuboid is $8$cm, breath is $6$cm, and height is $7$cm.

We have to find the surface area of the cuboid.

As we know that the formula is used to calculate the surface area of the cuboid is:

$SA=2lw+2lh+2hw$

where,

$l=length\\w=width\\h=height$

We are solving in the following way:

In this problem we have,

The length of the cuboid is $8$cm, breath is $6$cm, and height is $7$cm.

So, the surface area of the cuboid will be:

$SA=2lw+2lh+2hw$

$=>SA=2(lw+lh+hw)\\=>SA=2(8\times6+8\times7+7\times6)\\=>SA=2(48+56+42)\\=>SA=2(146)\\=>SA=292$

Hence, the surface area of the cuboid is$292cm^{2}$.
