Can someone help me find the volume of these?
snow_lady [41]
The volume of the triangular prism is:
 
V = (1/2) * (b) * (h) * (H)
 Where,
 b: base of the triangle
 h: triangle height
 H: prism height
 Substituting:
 V = (1/2) * (9) * (12) * (19)
 V = 1026 cm ^ 3

 
The volume of the cylinder is:
 
V = (pi) * (r ^ 2) * (h)
 Where,
 r: radio
 h: height
 Substituting:
 V = (3.14) * ((14/2) ^ 2) * (11)
 V = 1692.46 yd^3
