A metal feeding trough is in the shape of a triangular prism with one of the faces missing. The

base of the trough is an equilateral triangle with sides of length 3. 5 feet and a height of 4 feet.

If the trough is 15 feet long, how much metal was used to construct the trough?


66. 5 ft

119 ft

171. 5 ft

194 ft


Sagot :

It looks like the finals are a triangle assembled by an ensemble. If yes, then each end has area

4 * 3.5 + 3.5^2/4 √3

The sides are

  • Two reais each 3.5*15
  • Two can be each 4*15

Then some all areas = 119 ft

If I got the shape wrong, it's because an equilateral triangle of side 3.5 cannot have height 4.
