Answer:
Step-by-step explanation:
to find the answer you have to find the vulume and then divide by 450
O definitely does. I think Z and W do as well.
Y, K and P don't because they can't be rotated and map onto themselves.
Answer: 20 ft³
Step-by-step explanation:
volume of triangular pyramid = ![\frac{1}{3} bh](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B3%7D%20bh)
- b = base area = 10 ft
- h = height = 6 ft
Therefore, the volume is:
![\frac{1}{3} *10*6=\frac{1}{3}*60=\frac{60}{3}=20](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B3%7D%20%2A10%2A6%3D%5Cfrac%7B1%7D%7B3%7D%2A60%3D%5Cfrac%7B60%7D%7B3%7D%3D20)
Answer:
Surface area of prism=![2(l+w)h+2(lw)](https://tex.z-dn.net/?f=2%28l%2Bw%29h%2B2%28lw%29)
Step-by-step explanation:
We are given that surface area of rectangular prism=![2(lw+lh+wh)](https://tex.z-dn.net/?f=2%28lw%2Blh%2Bwh%29)
We have to write an expression that represents the surface area of prism.
Base of prism is made from length and width
Perimeter of base =2(l+w)
Area of base=lw=Area of top
Surface area of prism=Perimeter of base multiply by height+2 area of base
Because area of base and area of top are equal.
Surface area of prism=Ph+2B=2(l+w)h+2(lw)

Answer:
$400
Step-by-step explanation:
If the price after taking 25% off is $300, then $300 is 75% of the original price.
$300 = 0.75p
$300/0.75 = p = $400
The original price was $400.
_____
<em>Check</em>
0.25 × $400 = $100
$400 -100 = $300 . . . . the price after taking 25% off
