2.) What is the surface area of this triangular right prism?

228

Step-by-step explanation:

first we will find the area of the triangles on the sides of the prism.

(triangle area formula: (b*h)/2)

(6*5)/2 = 15

we multiply this by 2 since there are 2 sides that contain the same measures:

15*2 = 30

then we find the rectangles that are on the sides (not the base)

(rectangle formula: b*h)

11*6.5 = 71.5

multiply this by 2 since there are two sides:

71.5*2 = 143

finally we find the base using the same formula as we did to find the rectangles:

11*5 = 55

finally we add them all up:

30+143+55 = 228

hope this helps! :)

46 dollars is the answer.

step-by-step explanation:

6*6 = 36,         36+10=46
