Answer:
240m
Step-by-step explanation:
Volume is length x width x height
7.5m x 4m x 8m: 240m

0.95 in simplest form is 19/20
An equation says that two things are equal. It will have an equals sign (assuming you know what that is) like this:
7+2=10-1
What the equal says on the left, is equal to the answer on the right.
Basically, it's a statement saying "equals that"
