Answer:
Hence the disagree with Ima. He used the wrong formula to find the total surface area
Step-by-step explanation:
Surface area of the triangular prism = 2B + pH
B is the base area= 1/2 * 13 * 5
B = 65/2
B = 32.5 m^2
p is the base perimter = 5 + 12 + 13
p = 30m
H is the height of the prism = 8m
Substitute
TSA = 2(32.5) + 30(8)
TSA = 65 + 240
TSA = 305m^2
HEnce the total surface area is 305m^2
Hence the disagree with Ima. He used the wrong formula to find the total surface area
