Question 10 of 3What is the surface area of the solid?OA. 236 square centimetersOB. 112 square centimetersO C. 180 square centimetersOD. 292 square centimeters

Answer 1

Given: A cuboid with dimensions 8cm, 7 cm and 6 cm.

Required: Surface area of cuboid.

Step-by-step explanation:

Length of cuboid, l = 8cm

Breadth of cuboid, b = 7cm

Height of cuboid, h = 6cm

Surface area of a cuboid is

`\begin{gathered} S=2(lb+bh+hl) \\ S=2(8*7+7*6+6*8) \end{gathered}`

Calculating

`\begin{gathered} S=2(56+42+48) \\ S=2(146) \end{gathered}`

So surface area is

`S=292\text{ sq cm}`

Final Answer: Option D is correct answer.
