The above image is a silo made from two right circular cones, and a right circular cylinder where the dimensions are given in feet. Of the following answers, which one best represents the volume of the entire silo in cubic feet? The number of square units in the surface area of a cube is twice as large as the number of cubic units in its volume. What is the cube's volume, in cubic units? The number of square units in the surface area of a cube is given by the formula 6s 2 , where s is the length of the side of the cube in units. Moreover, the number of cubic units in a cube's volume is equal to s 3. Since the number of square units in the surface area is twice as large as the cubic units of the volume, we can write the following equation to solve for s:.
