How would you figure out the volume of a triangle? i've been wondering how for a while and the time's come to ask.

Well a triangle is a 2d figure, so it has no volume. The area of a triangle however is 

0.5 x base x height

Idon’t feel like doing the math but you need to do 2.24 divided by 7

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
