Number 8)... can y'all show your work if possible??
First, find the area of the triangular base of the prism:A = (a b)/2A = (22 26)/2A = 572/2A = 286Then, multiply the area you just found by the height of the prism to find its volume:V = A hV = 286 30V = 8580 <----- this is the answerI hope this helps. =)
