Answer:
243cm^3
Step-by-step explanation:
By Pythagoras' Theorem,
height of the prism ^2 + 5.4^2 = 7.8^2
height of the prism = ±√(7.8^2 -5.4^2) = ±5.6285cm (5s.f.) (rej. - 5.6285 since height > 0cm)
volume of the prism = 1/2 x 5.4 x 5.6285 x 16 = 243cm^3 (3s.f.)

Answer:
If this is asking you to simplify, it's easiest to focus on one thing at a time and taking your steps slowly.
Step-by-step explanation:
First, put each letter variable in an organized manner to help yourself simplify (this isn't required, but it's helpful):
- 5ck - ck + 4c + 8k + 1
Then, take it slowly and simplify/combine the like terms:
- 6ck + 4c + 8k + 1
Hopefully that was the answer you were looking for!
