Volume of prisms :(

I totally suck as i've been off for 3 weeks.

Right I have an Isosoles (sp?) triangle. The height is 24m , width 20 m , length 30m and one side of the triangle is 26m

Anyone help?

Ummm.. have you done tan, sin, cos? It might help if you have.

Yeah but only briefly and that was over a year ago now

easy, base volume x length so its: (26x26x20)x 30= 1014m2

(as long as the measurements and labels you typed are correct)

Isn't it cross section x length?

Isn't it cross section x length?

Cross section=base volume

Oh and I typed the formula wrong, It should be (1/2(24x20))x30=7200m2
