Answer:
24 cubic units
Step-by-step explanation:
The first prism has 20 cubic units and all you have to do is add 4 more cubic units and you will get 24 cubic units.
The longest of the four side lengths is 24 cm
<h3>How to find the value of the longest of the four side lengths?</h3>
The given parameters are:
Perimeter, P = 90 cm
The lengths are consecutive integers
Let the smallest be
Smallest = x
So, we have
P = x + x + 1 + x + 2 + x + 3
Evaluate the like terms
P = 4x + 6
Substitute P = 90 cm in P = 4x + 6
4x + 6 = 90
Subtract 6 from both sides
4x = 84
Divide by 4
x = 21
The longest side is
Longest = x + 3
This gives
Longest = 21 + 3
Evaluate
Longest = 24
Hence, the longest of the four side lengths is 24 cm
