Answer:
a₄₂ = 107
Step-by-step explanation:
The nth term of an arithmetic sequence is
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Given a₂₇ = 66 , then
a₁ + 26d = 66 , that is
- 12 + 26d = 66 ( add 12 to both sides )
26d = 78 ( divide both sides by 26 )
d = 3
Then
a₄₂ = - 16 + (41 × 3) = - 12 + 123 = 111
So you need to find the volume for the rectangular prism (1) and the rectangular prism in the center of it (2)
The formula for a rectangular prism is:
V = lwh [Volume = length x width x height]
1.
l = 15
w = 6
h = 6
V = lwh Plug in the numbers
V = (15)(6)(6) = 540
2.
l = 15
w = 4
h = 4
V = lwh
V = (15)(4)(4) = 240
Next you subtract the volumes by each other because the rectangular prism in the center(2) is the hole/empty part of the rectangular prism(1)
V = V(1) - V(2)
V = 540 - 240
V = 300
Answer:
