Volume of large box: 4 1/2 x 5 x 3 1/4 = 73.125 cubic inches

volume of small cube: 1/4^3 = 0.015625 cubic inches

to find quantity needed divide large by small:

73.125 / 0.015625 = 4680

 you need 4,680 small cubes

To find volume, multiply length x width x height.

4 1/2 x 5 x 3 1/4
4.5 x 5 x 3.25 = 73.125

1/4 = 0.25

Divide the total of the large cube to the small cube.

73.125/0.25 = 292.5

292 and 1/2 of the small cube(s) are needed to fill the right rectangular prism.

hope this helps

Rico and his friend eat some lasagna. Rico eats 1/9 of lasagna, and his friend eats 1/18 of the lasagna. How much of the lasagna
Blizzard [7]

Answer:

\frac{5}{6} of the lasagna is left

<u>Step-by-step explanation:</u>

Given:

Amount of lasagna Rico eats = 1/9

Amount of lasagna His friend eats = 1/18

To Find:

The amount  lasagna is left =?

Solution:

Total lasagna ate by both Rico and his friend = Amount of lasagna Rico eats +  Amount of lasagna His friend eats

Total lasagna ate by both Rico and his friend = \frac{1}{9} + \frac{1}{18}

Total lasagna ate by both Rico and his friend = \frac{2}{19} + \frac{1}{18}

Total lasagna ate by both Rico and his friend = \frac{3}{18}

Total lasagna ate by both Rico and his friend = \frac{1}{6}

The amount  lasagna is left = 1 - Total lasagna ate by both Rico and his friend.

The amount  lasagna is left = 1 - \frac{1}{6}

The amount  lasagna is left =\frac{6-1}{6}

The amount  lasagna is left =\frac{5}{6}

Can someone explain how the following Matrix can be multiplied? I thought the column of the first matrix had to match the row of
natita [175]

You are correct in thinking that the columns of the first matrix must match with the rows of the second matrix.

So for example, we can multiply a 1 x 5 matrix with a 5 x 7 matrix. The two matching '5's are directly what make multiplication possible in this case. For your problem, the first two '3's match and multiplication is possible.

The rows of the first matrix don't need to match with the columns of the second matrix.
