Julia needs to make a box in the shape of a rectangular prism with a height of 3 inches and a volume of 243 cubic inches. the dimensions, in inches, must be whole numbers greater than 1. julia claims that the length and the width must be equal. part a: what dimensions would support julia's claim about the length and with of the box? part b: what dimensions would not support julia's claim about the length and width of the box. part a length = part a width= part b b width=

The volume of a rectangular prism is equal to length*width*height. In this case, we have V = 243 and H = 3.
243 = LW(3), so LW = 81, where L & W are whole numbers greater than 1. There are only 3 possible pairs of values for this: 27*3, 9*9, and 3*27 (we cannot use 1*81 or 81*1, since we need dimensions > 1).
Part A. This could be true if Length = 9 in and Width = 9 in, as 9*9 = 81.
Part B. The claim could be false if Length = 27 in and Width = 3 in, as 27*3 = 81, but 27 is not equal to 3.
*Note that the width cannot be longer than the length.

Part A.
 sqrt 81 = 9; L = 9 ; W = 9 inches

Part B.
if length =27 , width =3, though 27*3 = 81 but then 27 is not equal 3. So false

Step 1: write equation

3(5)+3x=40-4

Step 2: simplify

15+ 3x= 36

Step 3: subtract 15 from both sides

3x-15=36-15

3x= 21

Step 4: get x alone

3x/3=21/3

x=7

Based on the data, each necklace is worth $7.00

don't forget to check!

3(5)+3(7)=36
15+21=36
36=36
