    Volume of Oblique Solid \[\Large V = A*H\] A = area of base H = height of solid

    I'm just realizing they gave you the area of the base of the cone

    so Area of cone = (1/3)*(area of base)*(height) Area of cone = (1/3)*(5)*(10) Area of cone = ???

    `b. a rectangular solid with a base of 5cm2 and height of 10cm` area of rectangular solid = (area of base)*(height) area of rectangular solid = (5)*(10) area of rectangular solid = ??
