OpenStudy (help!!!!):

Just find the area of each shape on the triangular prism

OpenStudy (help!!!!):

After you find the area of each shape, add them together

OpenStudy (timmyk14):

Area = base * height

With the numbers that have already been provided?

OpenStudy (help!!!!):

yes @vanessarose1

One triangle (sides)- 6 * 8 divided by 2 48/2 = 24 There's two of these triangles so we double this. The two side triangles measure up to 48 meters. Now for the top rectangle. The dimensions are 10 by 17. So we multiply 10 by 17 and get 170. Once again there's two of these. So double 170 and get 340. Now for the smaller rectangle. The dimensions for that are 6 by 17. Multiply these. 6 * 17 = 102. Add all the values. 48 + 340 + 102 = ? You answer that XD

OpenStudy (timmyk14):

Can I have a medal please

OpenStudy (timmyk14):

WAIT I MESSED UP!

OpenStudy (timmyk14):

Triangles (Both)- 48m Top Rectangle- 170 Bottom Rectangle- 136 [(8)(17)] Smaller Rectangle- 102 Add these; 48 + 170 + 136 + 102 = ?

Oh okay, I understand now! Thank you so much! I'll give you a medal! @Timmyk14

OpenStudy (timmyk14):

Thanks! I thought that the hypotenuse of the side triangles measured the same as the base of the triangle XD Silly me. Good thing I checked my work
