Question

Numbers are 6cm 7cm and 8cm if u cant see 6 at top 8 at bottom

Answer 1

In the prism, the measures of each side are:

length = 8 cm

width = 6 cm

height = 7 cm

The formula in getting the surface area of a rectangular prism is:

`SA=2(lw+lh+wh)`

Since we already have the values of length, width, and height, let's plug them into the formula above.

`\begin{gathered} SA=2lw+2lh+2wh \\ SA=2(8cm*6cm)+2(8cm*7cm)+2(6cm*7cm) \end{gathered}`

Then, solve.

`\begin{gathered} SA=2(48cm^2)+2(56cm^2)+2(42cm^2) \\ SA=96cm^2+112cm^2+84cm^2 \\ SA=292cm^2 \end{gathered}`

Therefore, the surface area of the prism is 292 square centimeters.
