Answer: Two regular octagons and eight congruent rectangles
Step-by-step explanation:
An octagon has 8 sides and the shapes on the bottom of the shape are 8 rectangles.
5 + 8s = 15 + 3s
8s - 3s = 15 - 5
5s = 10
s = 10/5
s = 2 <=== they will charge the same at 2 sq ft
V of rec. prism = whl = 3x5x6 = 90
V of cone = 3.14 x (3)^2 (8) /3= 75.36
90 - 75.36 = 14.64
answer
14.64

Answer: 3
Step-by-step explanation:
The question is to calculate one-eight of the sum of 18 and the product of 6 and 1. This will be:
= 1/8 [18 + (6 × 1)]
= 1/8 [18 + 6]
= 1/8 × 24
= 3
The answer is 3.
