Answer:
<u>808.5 m³</u>
Step-by-step explanation:
Volume of a Triangular Prism :
<u><em>Volume = 1/2 × b × h × l</em></u>
<u><em /></u>
=============================================================
Given :
⇒ b = 11 m
⇒ h = 10.5 m
⇒ l = 14 m
===========================================================
Solving :
⇒ V = 1/2 × 11 × 10.5 × 14
⇒ V = 7 × 115.5
⇒ V = <u>808.5 m³</u>

Answer:
Step-by-step explanation:
<u>Given AP with:</u>
- a₁= 28, aₙ = 79, Sₙ = 963
<u>Use the formula:</u>
- Sₙ = 1/2n(a₁ + aₙ), sum of the first n terms
<u>Substitute given values and solve for n:</u>
- 963 = 1/2n(28 + 79)
- 963 = 1/2n(107)
- 1/2n = 963/107
- 1/2n = 9
- n = 9*2
- n = 18
