Best ResponseYou've already chosen the best response.0That thing gives me a headache! Looking at the left hand side where the side is the hypotenuse of a right triangle the length would be:\[5^{2}+8^{2}=x ^{2}\] or that dimension is the sq rt 89 around 9.43 cm BUT the diagram show the side on the right at 10 cm.

Best ResponseYou've already chosen the best response.0Any you find the area of the triangle face then multiply that by the heigth of the prism that would give you volume, but there is something I am not seeing. The lower triangle is an equilateral as all three sides have the tick mark. Area of triangle A=1/2 B H. The base is given as 6cm, the height can be calculated as follows:\[h ^{2}=3^{2}+10^{2}=109\]\[h=\sqrt{109}=10.44\] So the area =.5 X 6 X 10.44 =13.22 CM SQ
