Question

Each dimension of a rectangular prism is increased by 80%. What percent of the original volume is the volume of the new prism?

51.2 percent

324 percent

583.2 percent

64 percent

Answer 1

I got 583...am I correct?

Answer 2

Rectangular Prism = Length*Base*Height = (9/5)^3 LBH = 729/125 = 5.832..

Yes you are right..

Answer 3

let's assign some values to make it easier
volume = length x width x height

let's say length = 2
width = 3
height = 4

if i increase by 80%
length = 3.6
width = 5.4
height = 7.2

new volume = 139.968 this is 583.2% of the original volume so you're right

Answer 4

Yay. just checking. thank you

Answer 5

one more question please? Part 1: Create and provide the dimensions for two similar figures of your choosing.
Part 2: What is the similarity ratio of these figures along with the ratio of their surface area and volume?
Part 3: Show your work, either using the actual volumes or using the formula, that the volume ratio is true.
