A rectangular prism has a volume of 640 cubic centimeters, a height of 5 centimeters, and a length of 8 centimeters. What is the width of the rectangular prism in centimeters?

10 cm

Step-by-step explanation:

The volume of a rectangular prism is calculated by multiplying the length, width and height together. So, to find one of the dimensions, all we need to do is divide the volume by the given dimensions. In this case we divide the volume, 640, by the height, 5, and length, 8.

The width, or w, is equal to 640 divided by 5 and 8.

w = 640 ÷ 5 ÷8

w = 80 ÷ 8

w = 10

The width is 10 cm.

I hope this helps ^^ Good luck n.n

b.) 160 miles on a 5 gallons car

step-by-step explanation:

240/10=24 miles/gallon

160/5=32 miles/gallon

30/1=30 miles/gallon

168/6= 28 miles/gallon

32 miles/gallon is the most amount, so this is the best.
