Hey there :)
We know the volume formula of a triangular prism
Volume = base area × height of prism
We are given:
Base of triangle = 5 ft
Height of triangle = 3 ft
Height of prism = 7.5 ft
Apply the formula
V =
( 5 )( 3 ) × 7.5
= 7.5 × 7.5
= 56.24 ft³

-7n-15≤21. find n
❖ Add 15 to both sides:-
-7n≤21+15
-7n≤36
❖ Now divide by -7 on both sides:-
n≥-5.14 or
n≥-5
The inequality sign changed because we divided both sides by a negative number.
