V = B * H
B = 1/2 * b * h

b = 0.68
h = 49 cm = 0.49m
B = 1/2 * 0.68 * 0.49
B = 0.3332/2
B = 0.1666

V = B * H
B = 0.1666
H = 1.3

V = 0.1666 * 1.3
V = 0.21658 cubic meters
The answer is 0.217m^3 bc they are asking for CUBIC METER so you have to CONVERT cm to meters. 1cm=0.01m so multiple that by 49cm.
By the way, the formula to find that shape is 1/2*a*c*b.
