Answer 1

To find the volume of the triangular planting trough, we need to first find the area of the triangular base and then multiply it by the depth.

The area of a triangle can be calculated using the formula A = 0.5 * base * height. In this case, the base is 1.2 m and the height is 0.75 m (since it is the depth of the trough).

A = 0.5 * 1.2 m * 0.75 m
A = 0.45 square meters

Now, to find the volume of the trough, multiply the area of the base by the depth:

V = 0.45 square meters * 3.5 m
V = 1.575 cubic meters

Therefore, the correct response is:

1.575 cubic m
