Question

The base of a monument at Veterans Park is shaped like a rectangular prism with a base of 5 meters by5 meters and a height of 3.2 meters. What is the surface area, in square meters, of the prism?3.2 m5 m5 m

Answer 1

The rectangular prism has the following dimensions;

`\begin{gathered} \text{height}=3.2m \\ \text{length}=5m \\ \text{width}=5m \end{gathered}`

The total surface area of

`\begin{gathered} TSA_{rec\tan gular\text{ prism}}=2(lw+lh+wh) \\ \text{Where l= length} \\ w=\text{width} \\ h=\text{height} \end{gathered}`
`\begin{gathered} TSA_{rec\tan gular\text{ prism}}=2((5*5)+(5*3.2)+(5*3.2)) \\ TSA_{rec\tan gular\text{ prism}}=2(25+16+16) \\ TSA_{rec\tan gular\text{ prism}}=2(57) \\ TSA_{rec\tan gular\text{ prism}}=114m^2 \end{gathered}`

The total surface area of the rectangular prism is 114 square meters
