To find the volume of the triangular planting trough, we need to first calculate the area of the triangular base.
The area of a triangle is given by the formula: A = 1/2 * base * height
In this case, the base is 1.2 m and the height is 0.75 m.
A = 1/2 * 1.2 * 0.75 = 0.45 square meters
Now that we have the area of the base, we can calculate the volume of the triangular trough by multiplying the area of the base by the length of the trough (3.5 m):
Volume = area of base * length = 0.45 * 3.5 = 1.575 cubic meters
Therefore, the triangular planting trough will hold 1.575 cubic meters of salt.
This triangular planting trough is 3.5 men long 1.2 M wide and at the top and 0.75 m deep how much salt will it hold
