SA= 144

Answer 2

Volume = 66

Surface are = 144

Explanation:

1. Volume

The formula to find the volume of a triangular prism is the following,

`A=(l*w*h)/(2)`

The following information is given,

lenght = 4

width = 11

hieght = 3

Substitute these numbers into the formula and solve for the heihgt,

`A=(l*w*h)/(2)\\\\A=(4*11*3)/(2)\\\\A=66`

2.Surface area

The surface area of a figure is the two-dimensional distance around the figure. It can be found by finding the area of each face of the figure and then adding the result up.

The formula to find the area of a rectangle is the following,

`A_r=(lenght)(width)`

The formula to find the area of a triangle is the following,

`A_t=((legnth)(width))/(2)`

Substitute in the give values and add up the results to find the total surface area of the rectangle,

`((5)(11))+((4)(11))+((3)(11))+(((3)(4))/(2))+(((3)(4))/(2))\\\\=55 + 44 + 33+ 6 + 6\\\\= 144`
