Answer:
The volume of the composite figure is:
Step-by-step explanation:
To identify the volume of the composite figure, you can divide it in the known figures there, in this case, you can divide the figure in a cube and a pyramid with a square base. Now, we find the volume of each figure and finally add the two volumes.
<em>VOLUME OF THE CUBE.
</em>
Finding the volume of a cube is actually simple, you only must follow the next formula:
- Volume of a cube = base * height * width
So:
- Volume of a cube = 6 ft * 6 ft * 6 ft
- <u>Volume of a cube = 216 ft^3
</u>
<em>VOLUME OF THE PYRAMID.
</em>
The volume of a pyramid with a square base is:
- Volume of a pyramid = 1/3 B * h
Where:
<em>B = area of the base.
</em>
<em>h = height.
</em>
How you can remember, the area of a square is base * height, so B = 6 ft * 6 ft = 36 ft^2, now we can replace in the formula:
- Volume of a pyramid = 1/3 36 ft^2 * 8 ft
- <u>Volume of a pyramid = 96 ft^3
</u>
Finally, we add the volumes found:
- Volume of the composite figure = 216 ft^3 + 96 ft^3
- <u>Volume of the composite figure = 312 ft^3</u>
Answer:
Dylan
Step-by-step explanation:
Rate of Origami Making
1) June
= 10/30
= 1/3 origami birds per minute
2) Dylan
= 4/10
= 2/5 origami birds per minute
2/5 > 1/3
So Dylan was faster.
Answer:
See below
Step-by-step explanation:
To begin, it is volume, not area
1. 8 x 12 x 17 = 1632 in ^3
5. 9 x 9 x 13.5 = 1093.5 in^3
If you want to find SURFACE AREA:
1. 2(8 x 12) + 2(8 x 17) + 2(17 x 12) = 872 in^2
5. 2(9 x 9) + 4(9 x 17) = 774 in^2
