A 60 cm long wire is welded into a cube model. What is the surface area and volume of the cube? A school uses lime to paint the four walls and ceiling of the classroom. The room is 8 meters long, 6 meters wide and 4 meters high, deducting 15 square meters of doors and windows. If 0.25 kg of lime is used per square meter, how many kg of lime do you share? I'll see you later, little sister!

1、60/12=5cm
Surface area: 5 * 5 * 6 = 150 square centimeter
Volume: 5 * 5 * 5 = 125 CC
2、（8*4+6*4）*2+8*6-15
=112+48-15
=160-15
=145 square meters
145*0.25=36.25kg

With a 12 decimeter long wire welded into a largest cube model, the volume of the cube model is () cubic decimeter, the surface area is
() square centimeter

12 △ 12 = 1 decimeter
1 × 1 × 6 = 6 square decimeters
1 × 1 × 1 = 1 cubic decimeter
A 12 decimeter long iron wire is welded into the largest cube model. The volume of the cube model is (1) cubic decimeter, and the surface area is (6 square decimeter)
