Answer:
Volume = 9900 ft2
Step-by-step explanation:
To find the volume of the pool, we can use the base as the trapezoid, and then we need to calculate the base area and multiply by the height.
The trapezoid has a bigger base of 8 and a smaller base of 3, with a height of 60, so the area is:
Area = (8+3)*60/2 = 330 ft2
Now, to find the volume, we just need to multiply the base area by the height of 30 feet:
Volume = Area * Height = 330 * 30 = 9900 ft2
1.) Convert the measurements of Naomi's pets so that the two has the same unit of measurements. I will use cm.
1 mm = .01 cm;
Therefore: 40 mm = 4 cm is the length of the fish
2.) Subtract the pets' measurements:
25 cm - 4 cm = 21 cm
3.) Therefore, Naomi's guinea pig is 21 cm longer than her fish.
