his triangular planting trough is 3.5 m long, 1.2 m wide at the top, and 0.75 m deep. How much soil will it hold?
To calculate the volume of the triangular planting trough, first calculate the area of the trough's cross-section at the top using the formula for the area of a triangle:
Area = 0.5 * base * height
Area = 0.5 * 1.2 m * 0.75 m
Area = 0.45 m²
Then, multiply the area of the cross-section by the length of the trough to find the volume:
Volume = Area * length
Volume = 0.45 m² * 3.5 m
Volume = 1.575 m³
Therefore, the triangular planting trough will hold 1.575 cubic meters of soil.
To find the volume of a triangular prism, you must first find the area of the triangular base then multiply by the height of the prism.(1 point)

Yes, I am sure. To find the volume of a triangular prism, you first need to find the area of the triangular base by using the formula for the area of a triangle:
Area = 0.5 * base * height
Then, you multiply the area of the triangular base by the height of the prism to calculate the volume:
Volume = Area of base * height
This is the correct formula for finding the volume of a triangular prism.
