Answer 1

Given:

The shape is:

Find-:

The surface area of the shape

Explanation-:

Surafce area of a shape is:

`\text{ Surface area }=2(lw+wh+lh)`

Where,

`\begin{gathered} l\text{ = Length} \\ \\ w=\text{ Width} \\ \\ h=\text{ Height} \end{gathered}`

So, the surface area is:

`\begin{gathered} \text{ Length }=5\text{ cm} \\ \\ \text{ Width }=4\text{ cm} \\ \\ \text{ Height }=2\text{ cm} \end{gathered}`

So, surface area is:

`\begin{gathered} \text{ Surface area }=2((5*4)+(4*2)+(5*2)) \\ \\ \text{ Surface area }=2(20+8+10) \\ \\ \text{ Surface area }=2(38) \\ \\ \text{ Surface area }=76\text{ cm}^2 \end{gathered}`

The surface area is 76 cm²
