The frustum can be considered as consisting of a square pyramid, less the
cut volume.
- The mass of the stand, is approximately 18.60905 kg
Reasons:
The given parameter of the frustum are;
The density of the frustum, ρ = 85 g/cm³
Height of pyramid, h = 9 cm
Side length of base = 10 cm
Height of frustum
By proportional shapes, the side length of the top of the frustum can be found as follows;
B₁ = 10², B₂ = 
Therefore;
The volume of the stand, V ≈ 218.93 cm³
Mass = Volume × Density
∴ Mass of the stand, m = 218.93 cm³ × 85 g/cm³ = 18,609.05 grams = 18.60905 kg.

1) online has the lower unit price
27.25 / 5 = 5.45
32.16 / 6 = 5.3583333.... rounded it would be
5.35
2) The cost of 7 pounds would be 103.18
73.70 / 5 = 14.74 (cost of one pound)
14.74 x 7 = 103.18
3) The scarf in October costed more
13.35 / 3 = 4.45 (one scarf)
22.65 / 5 = 4.53
hope this helps
Answer:
B. 0.50
Step-by-step explanation:
It claims to estimate. Square root of 2 would be somewhere around 1. Square root of 5 would be somewhere around 2. Then you divide, 1/2, and that should equal 0.50.
I hope this is correct!
