The dimensions of a triangular prism are shown in the diagram. What is the
total surface area of the triangular prism in square centimeters?"

I need helppp

D

Step-by-step explanation:

SA = bh + (s1 + s2 + s3)H is the formula to find out the surface area

b is base, h is height (small height), s's are the sides, H is the height (longer one)

SA = 12(9) + (10 + 10 + 12)32

SA = 108 + (32)32

SA = 108 + 1024

SA = 1132

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
