Question

What is the surface area, measured in square centimeters, of the shapebelow? Do not include units in your answer.

Answer 1

The figure in the question is a cuboid with

length = 7 cm, width = 3cm and height = 4cm

Surface area of a cuboid is given as

`\begin{gathered} S=2(lw+lh+wh) \\ S=2((7*3)+(7*4)+(3*4))_ \\ S=2(21+28+12) \\ S=2(61) \\ S=2*61 \\ S=122cm^2 \end{gathered}`

Hence the answer is 122 square-centimeters
