Question

The triangular bases of a triangular prism have three congruent sides, each measuring 10 centimeters. The height of each of the triangular bases is approximately 8.7 centimeters. The height of the prism is 15 centimeters. What is the approximate surface area of the prism? 450 cm2 450 cm3 537 cm2 537 cm3

Answer 1

Answer:

537 cm2 is your answer. Hope this helps. : 0

Answer 2

We know that

[surface area ]=2*[area of the base]+[perimeter of the base]*height
area of the base=10*8.7/2-----> 43.5 cm²
perimeter of the base=10*3----> 30 cm
height of the prism=15 cm
[surface area ]=2*[43.5]+[30]*15------->537 cm²

the answer is
the approximate surface area of the prism is 537 cm²
