What is the volume of a rectangular prism with the dimensions: base 3 1/4 cm, 2 1/2 cm, 4 1/2 cm? Please Help Me!
Thanks oobleck, typing without looking at the keyboard with thick fingers is not good.
apparently, without looking at the screen, either!
Thanks! You guys are lifesavers!
V = (3 1/4)(2 1/2)(4 1/2)
is it the mixed fractions that cause the problem
you might switch them to decimals ...
V = (3/25)(2/5)(4/5)
=
or, for those of us who use actual decimal points,
V = (3.25)(2.5)(4.5)
or (13/4)(5/2)(9/2)

To find the volume of a rectangular prism, you need to multiply the length, width, and height of the prism. In this case, the length is 3 1/4 cm, the width is 2 1/2 cm, and the height is 4 1/2 cm.
To multiply mixed numbers, convert them into improper fractions first.
The length can be expressed as 3 1/4 cm, which is equivalent to (3*4 + 1)/4 = 13/4 cm.
The width can be expressed as 2 1/2 cm, which is equivalent to (2*2 + 1)/2 = 5/2 cm.
The height is already in improper fraction form, 4 1/2 cm = (4*2 + 1)/2 = 9/2 cm.
Now, multiply the three dimensions together: (13/4 cm) * (5/2 cm) * (9/2 cm).
To multiply fractions, multiply the numerators together and multiply the denominators together: (13 * 5 * 9) / (4 * 2 * 2).
Calculate the numerator: 13 * 5 * 9 = 585.
Calculate the denominator: 4 * 2 * 2 = 16.
So, the volume is 585/16 cm^3.
