I need help with math homework

1) 2.6 ft³

Step-by-step explanation:

for the first one, multiply height times width times depth divided by two, since it is a triangle. Area of a triangle is always height times width divided by two.

So

(1.3 × 1 × 4)/2 = 2.6 ft³

The second one you can see as 6 of those triangle bars glued together, can you calculate the volume then?

you need to rotate this triangle about the origin 270 degrees clockwise to create the full square.
