Answer:
1. 600 cm^3
2. 24 cm^3
3. 540 cm^3
4. 1476 cm^3
Step-by-step explanation:
1. rectangular prism volume equation is: V = lwh, where l = length, w = width, h = height. Substitute known values into this equation: V = 5 x 8 x 15 and we get V = 600 cubic cm.
2. V = (1/2)bhl, where the base and height are dimensions of the triangle. V = (1/2)6 x 2 x 4 and we get V = 24 cubic cm
3. V = Bh, where B is the base area and h is the perpendicular height. V = 45(12). So, V = 540 cm^3
4. Same thing with this one: V = Bh. Substitute known values into this equation: V = 82(18), which means V = 1476 cm^3
