A Trough Has Vertical Ends That Are Equilateral Triangles with Sides

question 104

Short Answer

A trough has vertical ends that are equilateral triangles with sides of length $7 \mathrm { ft }$ . If the trough is filled with water to a depth of $4 \mathrm { ft }$ , find the force exerted by the water on one end of the trough. Round to one decimal place. (The weight density of water is $62.4 \mathrm { lb } / \mathrm { ft } ^ { 3 }$ .)
