Determine the volume of the following contianers
Solve
1. The volume of a rectangular prism is 4641 cm3. If the height is 13 cm, and the width is 21 cm, find it's length.
2. When Jill opened her favorite cereal box the other morning, she noticed that it wasn't filled all the way to the top. In fact it was only 78% filled. If the box was 8 cm long, 3 cm wide and 11.5 cm tall, how many cm3 of "air" were in her cereal box?
(to the nearest cm3)
3. Find the weight of a rectangular prism if it's length is 8 m, it's width is 4.5 m, and it's height is 3.5 m, if the contents weigh 0.03 kg per m3.
4. Peter has a tank measuring 90 cm x 60 cm x 75 cm. It is partly filled with water to a depth of 25 cm. He then fills the tank with water flowing at a rate of 4 litres per minute from a tap. How long will it take to fill the tank completely?
