Question

find the surface area of the cuboid whose measure are length=7cm breath=4cm height=3cm

Answer 1

Answer:

122cm^2

Explanation:

Given :

• Length,l = 7cm

• Breath,b = 4cm

• Height,h = 3cm

To Find :

• Surface area of the cuboid

Solution :

We know surface area of the cuboid => 2lb + 2lh + 2bh

Therefore,surface area of the given cuboid

=> 2(7)(4) + 2(7)(3) + 2(4)(3)

=> 56 + 42 + 24

=> 122cm^2

Hence,surface area of the given cuboid is 122cm^2

Answer 2

Answer: 2(7x4+4x3+3x7)

= 2(28+12+21)

=2x 61

= 122 cm²
