A rectangular flowerpot is 20 inches long 8 inches wide and 6 inches high.
true or false
if andy fills the flowerpot 2/3 fullof potting soil the expression 2/3(20 + 8 + 6) could be used to find the amount of potting soil he needed
Your expression will be correct if you multiply, rather than adding the dimensions.
2/3(20 * 8 * 6)
So false?
Yes, it's false.
True.
To find the amount of potting soil needed, we can calculate the volume of the rectangular flowerpot. The volume of a rectangular prism can be found by multiplying its length by its width and its height.
In this case, the length of the flowerpot is 20 inches, the width is 8 inches, and the height is 6 inches. So, the volume can be calculated as:
Volume = Length x Width x Height
Volume = 20 inches x 8 inches x 6 inches
Volume = 960 cubic inches
Now, if Andy fills the flowerpot 2/3 full of potting soil, we can use the expression 2/3(20 + 8 + 6) to find the amount of potting soil needed.
2/3 represents the fraction of the potting soil that will be filled. We multiply this fraction by the sum of the dimensions of the flowerpot (length + width + height).
2/3(20 + 8 + 6) = 2/3(34) = (2/3) * 34 = 22.67
Therefore, the amount of potting soil Andy needs is approximately 22.67 cubic inches.
