Question

The surface area of the prism is ______ square units. All measurements in the image below are in units. (Input whole number only.)

A triangular prism is shown with 2 right triangular sides having legs 3 and 4 and hypotenuse 5. The length of the prism is 3.5

Answer 1

area of prism=area of two triangles+area of three rectangles
\[area ~of ~two~triangles=2\times \frac{ 1 }{ 2 }\times 3 \times4=12 ~sq. units\]
area of first rectangle=3 *3.5=10.5 sq. units
area of second rectangle=4*3.5=14 sq.units
area of third rectangle=5*3.5=17.5 sq. units
area of prism=?
