Question

Find the surface area for the triangular prism below if AB = 16 m, AC = 33 m, AD = 12 m, and DP = 9 m. (Note: the bases are isosceles triangles.)

Answer 1

INFORMATION:

We have the following figure

And we must find its surface area

STEP BY STEP EXPLANATION:

To find the surface area of the triangular prism, we can divide the figure in:

- The two triangle bases:

We have the next triangle in the two bases:

We can calculate the area of the triangle

`A=(16*9)/(2)=72m^2`

Since we have the same triangle in the two bases, the total area of the two triangles would be

`72m^2\cdot2=144m^2`
