4. 64/16 = 4. It drops 16 feet per second and 64 feet in total. It takes 4 seconds for a dropped object to fall 64 feet.
5. This one is a bit tricky, but the height would be 3. The formula would be 3 * 9 * 9. The width and length would both be 9. The height would be 3. 9 * 9 * 3 = 243. The volume of the rectangular prism would be 243 cubic centimeters.
6. Okay. Let’s see. 233 - 64 = 169. 169 squares is 13. The longest edge of the deck is 21 feet, because 13 + 8 = 21. Taylor will need 21 feet of railing for the longest edge of her deck.
