Given: A cuboid with dimensions 8cm, 7 cm and 6 cm.
Required: Surface area of cuboid.
Explanation:
Length of cuboid, l = 8cm
Breadth of cuboid, b = 7cm
Height of cuboid, h = 6cm
Surface area of a cuboid is
[tex]\begin{gathered} S=2(lb+bh+hl) \\ S=2(8\times7+7\times6+6\times8) \end{gathered}[/tex]
Calculating
[tex]\begin{gathered} S=2(56+42+48) \\ S=2(146) \end{gathered}[/tex]
So surface area is
[tex]S=292\text{ sq cm}[/tex]
Final Answer: Option D is correct answer.
