solid mensuration problems with solutions plane figures
problems efficiently: Cube Volume = a³ Surface Area = 6a² Cuboid (Rectangular Prism) Volume = l × b × h Surface Area = 2(lb + bh + hl) Cylinder Volume = πr²h Surface Area = 2πr(h + r) Cone Volume = (1/3)πr²h Surface Area = πr(l + r), where l is the slant height Sphere Volume = (4/3)πr³
