Choose the matching base and perpendicular height, or count equal cube layers before multiplying dimensions.
In this one. A cube has equal length, width and height. Volume counts cubic units, so multiply the edge length three times.
Look for shapes drawn on a dotted or squared grid, sharing a side or a vertex, with names like ABCD and ABE. Words like "grid", "dots" or "squares" alongside a request to compare areas or heights are the giveaway.
Children measure height by eye along the slanted side of a shape instead of counting the straight up-down grid distance from the base to the opposite vertex, which gives the wrong height whenever a side leans.
