I'm guessing these are two questions? Anyway, to find the volume of most prisms, you just do base area into height. Here,we have our work cut out for us since we already have base area. For the one with the 9, 10 dimensions, the volume is (9x10) = 90cm^3 For the the one with the 14.5, 6 dimensions, the volume is (14.5x6) = 87cm^3
A planting bed contains 0.75 tons of soil. A landscaper will apply fertilizer to the bed. The directions say to apply 1 ounce of fertilizer for every 100 pounds of soil.
How many ounces of fertilizer should the landscaper apply?
