    Each CONE (am-4700_syc) is a yellow 1 ft. ¹³⁄₁₆ in. (~33 cm) tall rubber marker cone and weighs 1lb 7oz (~653 g). Each CONE has an 8⅜ in. (~21 cm) +/- ⅛in. (~3 mm) square base with ¼ in. (~7 mm) tall feet.

    Each CUBE (am-4700_bpc) is made of purple PVC fabric and is marked with a FIRST logo. The CUBE is a cube-like shape, inflated to 9 ½ in. (~24 cm) +/- ¼ in. (~6 mm) as measured from face to face, but these ship deflated. A CUBE has rounded corners, may not have flat surfaces, and the length, width, and height of the sides may not be equal dimensions. A CUBE weighs 2.5 oz (~71 g). 

    The Cube Measurement Jig (am-4700_cmj) is a tool developed by FIRST to calibrate CUBE inflation at events. The appropriate range for CUBE inflation is between when the cube can lift the jig off the ground due to it's inflation, and when the cube touches both sides of the jig at the same time. The total weight of the jig is important in determining the minimum bound.
