A right rectangular prism has a length of 5 cm, a width of 8 cm, and a height of 4 cm.What is the volume of the prism?

Enter your answer in the box.
I believe it is 160.

Answers

The formula for volume of a rectangular prism is length x height x width. Plug in the given information.

5 * 4 * 8

Now multiply:

5 * 4 = 20
20 * 8 = 160

Your answer of 160 was correct :) Good job

Please help! Hi, I'm stuck on a part of this question, we have to solve using Gauss Jordan Elimination: A corporation wants to lease a fleet of 12 airplanes with a combined carrying capacity of 220 passengers. The three available types of planes carry 10,15,20 passengers. How many of each type of plane should be leased?

Answers

Do common sense has anything to do with this question? Because
corporation might forget the arbitrary 12 airplane rule
and have 11 times 20 = 220.
But perhaps they get a discount if all 12 hangars are used!

Playing by the rules of the question:-
Let a, b, c be the aeroplanes that carry
10, 15, and 20 passengers, respectively,

a + b + c = 12
10a +15b +20c = 220

We may rearrange these as
4a + 4b + 4c = 48
2a + 3b + 4c = 44
Now subtract
2a + b = 4

There appear to be 3 options
a = 0, b = 4 which means 220 = 0*10 + 4*15 + 8*20
a = 1, b = 2 which means 220 = 1*10 + 2*15 + 9*20
a = 2, b = 0 which means 220 = 2*10 + 0*15 + 7*20

If you dismiss the ones with zeros it may be that
the expected answer to "How many of each plane" is

One that carries 10, 2 that carries 15, and 9 that carries 20

A rollercoaster ride reaches a height of 80 feet before it sharply drops. The height above the ground of the rollercoaster car during the drop is modeled by the function, h(t)=10t2−40t+80 , where t is measured in seconds since the car started its decline. The model is accurate for 0≤t≤4 . On this portion of the ride, how long does the car take to reach a minimum height from the ground before rising again?
