After cutting off a cuboid with a volume of 80 cubic meters from one end of a cuboid, there is just a cuboid with an edge length of 10 meters, which is the original cuboid volume What is the surface area? Learning needs


Rectangular bottom area 10x10 = 100 square meters
Height 10 + 80 △ 100 = 10.8m
Original volume 10.8x100 = 1080 cubic meters



When the height of a cuboid is increased by 5 meters, it becomes a cube, and the volume increases by 180 cubic meters. The original cuboid volume is ()


Length × width × 5 = 180
Length × width = 36
Know length = width = 6 from cube
Then the volume of the original rectangle = 36 × (6-5) = 36 cubic meters



A warehouse is 12m in length, 6m in width and 5m in width. How many cubic meters of wheat can the warehouse hold? Is it the volume or the volume of the warehouse
