Answer:
6 boys have brown hair.
Step-by-step explanation:
boys in the class.
boys have brown hair.
If we split this shape into 2 rectangles, we have 2 rectangles that each measure 10m x 20m x 200cm. 200 cm = 2 m. Volume is found by multiplying length times width times height. We have 2 shapes so we will have 2 volumes that we will add together to get a total volume. 10*20*2=400 m cubed. Two of those is 800 m cubed.
Answer:
256 cups
Step-by-step explanation:
In this question, we are asked to calculate the number of 8-ounce cups that each of the cooler of water will fill.
This is obviously a conversion type of question. We proceed as follows;
She buys 80 gallons to distribute in 5 coolers, this means each cooler will contain 80/5 = 16 gallons each of water.
Now let’s get the equivalent of this in ounce.
Mathematically, 1 gallon contains 128 ounces.
Since one cooler contains 16 gallons, this means each cooler will contain 16 * 128 = 2,048 ounces of water
Now, we know each cooler of water is to fill a series of 8- ounce cups. We now need to calculate the number of 8-ounce cups that will be filled by the 2,048 ounces cooler.
Mathematically, this is 2,048/8 = 256 cups
