How much material is needed to construct a triangular tent that is 10 feet wide, 12 feet tall, and 18 feet long with side measurements of 13 feet? 768 square feet 1024 square feet 1120 square feet 1392 square feet

The answer is " 768 square feet. ".

Total surface area of a triangular prism = width x height +(sum of sides + width) x length and here;

width = 10

height = 12

sides = 13

length = 18

= (10 x 12) + (13 + 13 + 10) x 18

= 120 + (36 x 18)

= 120 + 648

= 768 square feet.
