The volume of a rectangular prism is 270 cubic centimeters. The height of the prism is 5 centimeters. What should the length and width of the prism be? Explain your solution strategy.

Answers

V=volume h=height l=length w=width
V=h•w•l
w•l=v/5
w•l=270/5
w•l=54
Since this is all we know, we can't tell what the width or length really is but we can give examples: 6 and 9 (or 9 and 6), 4 and 13.5 (or the other way round), 18 and 3 (or 3 and 18), 2 and 27 (or 27 and 2).

5cm (H), 9cm (L), 6cm (W).

5 times 9 is 45 times by 6 (240 plus 30=) 270 CC

Or You could just have numbers for L and W which equal 54 because 5 times by 54 is 270.

For this question i just need help with part B. This is just the info from the question:Coach Wilson ordered t-shirts for the basketball team from two different t-shirt suppliers. One supplier charged $16 for each t-shirt as well as 5% for shipping. The other supplier charged $18 for each shirt plus 7% for shipping.

trever saves 2/3 of the money he earns at his after- school job. suppose Trevor starts saving 1/4 as much as he is saving now. which statement below is true? so will Trevor saves more or less?

Answers

so 1/4 is a fraction
a fractin is less than a whole
so if he saves a fraction of what he is savind now, then he is saving only a part of what he originally saved
he is saving less
TREVOR SAVES LESS

he will save less because a fraction of a fraction will always end up smaller if it isn't improper, so instead of saving 2/3 of his money, if my math is correct, he'd only be saving 1/6 of his paycheck

Can anyone help me with this
