Question

I need help with this and please write how you got the answer to this

Answer 1

Option C:

Laterals surface area = 144 square units

Total surface area = 186 square units

Solution:

Lateral surface area = (8 × 6) + (8 × 6) + (8 × 6)

= 48 + 48 + 48

= 144

Lateral surface area of the prism = 144 square units

Base area (B) =
`(1)/(2) bh`

`$=(1)/(2) * 6* 7`

= 21 square units

Total surface area = Lateral surface area + 2 (Base area)

= 144 + 2(21)

= 144 + 42

= 186

Total surface area of the prism = 186 square units.

Hence Option C is the correct answer.

Laterals surface area = 144 square units

Total surface area = 186 square units
