Ima mark as brainlist if u help plsss

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
