Question

Calcu!atenthe lateral area of the prism round to the nearest tenths

Answer 1

Given data:

The first base length is b=4.3 in.

The second base length is b'=5.4 in.

The third base lenght is b''=8.4 in.

The height is h=4.1 in.

The expression for the lateral surface area is,

`A=(b+b^(\prime)+b^(\doubleprime))h`

Substitute the given values in the above expression.

`\begin{gathered} A=(4.3\text{ in+5.4 in+8.4 in)(4.1 in)} \\ =(18.1\text{ in)(4.1 in)} \\ =74.21in^2 \end{gathered}`

Thus, the lateral surface area is 74.21 square-inches.
