A Trough Is Filled with a Liquid of Density $855 \mathrm {~kg} / \mathrm { m } ^ { 3 }$

Short Answer

A trough is filled with a liquid of density $855 \mathrm {~kg} / \mathrm { m } ^ { 3 }$ . The ends of the trough are equilateral triangles with sides $6 \mathrm {~m}$ long and vertex at the bottom. Find the hydrostatic force on one end of the trough.
