With 60 cm long wire welded into a cube frame, the surface area of the cube is () square centimeter?

With 60 cm long wire welded into a cube frame, the surface area of the cube is () square centimeter?

The sum of edge length of cube = 12a = 60 a = 5
The surface area of the cube is 6 * 5 * 5 = 150 square centimeters

With a 12 decimeter long wire, welded into a largest cube frame, the cube's edge length is () decimeter, the surface area is () square decimeter

With a 12 decimeter long wire, welded into a largest cube frame, the cube edge length is (1) decimeter, surface area is (6) square decimeter

Use a 96cm long iron wire to make a cube frame, and its edges are () cm long

A cube has 12 edges of equal length
So the edge length is:
96/12=8cm
