Jenny has a toy which is in the shape of a right prism with triangular bases. The sides of its bases are each 5 feet and its approximate height is 4.3 feet. The length of the prism between the bases is 12 feet. What is the approximate surface area of this right prism?

A. 150ft2 B. 201.5ft2
C.210ft2 D.225.4ft2

B

Step-by-step explanation:

split the triangle in to 5 different shapes

3 of them are rectangles, and 2 are triangles

all of the rectangles are the same size being:

12 by 5  so 12 times 5. then do this 3 times for each rectangle.

Now take the triangles and find the area for those.

which is 1/2 or base times height . so half of 5 multiplied by height (4.3)

being 2.5 times 4.3 giving you 10.75

now take the area of the rectangles and triangles and add them together

60+60+60+10.75+10.75= 201.5 ft2
