The dimensions of a right rectangular prism are shown below. 1 in. 1a in. 2 in. in. How many cubes with side lengths of inch are

Dafna1 [17]

First we neeed to find the volume of the rectangular prism

$V=\text{ l}\times w\times h$ $V=1\times1\frac{1}{6}\times2\frac{1}{6}$ $=1\times\frac{7}{6}\times\frac{13}{6}$ $=\frac{91}{36}in^3$

Volume of cube with side lengths 1/6 = 1/6 x 1/6 x 1/6 = 1/216

The number of cubes needed to fill the prism without gaps or overlaps =

$=\frac{91}{36}\text{ divide by }\frac{1}{216}$ $=\frac{91}{36}\times\frac{216}{1}$ $=\frac{19656}{36}$ $=546$

Which graph shows a linear function?

Stolb23 [73]

Answer:

Step-by-step explanation:

You have shared only one graph, that of a quadratic function with vertex at (0, 0) and an equation based upon y = ax^2, where a is a constant coefficient.

Please go back to the source of your question and describe the other graphs that were given to you.

The graph that shows a straight line is the linear function.

Red Perimeter= 4u X π= 4uπ

Blue Perimeter= u X π= uπ

Red Area= 2u X 2u X π= 4u2π

Blue Area= u X u X π= u2π
