Put four cubes with the edge length of 1 decimeter together to form a cuboid. The surface area of the cuboid may be______ Square decimeter, maybe______ Square decimeter

Put four cubes with the edge length of 1 decimeter together to form a cuboid. The surface area of the cuboid may be______ Square decimeter, maybe______ Square decimeter

There are two kinds of spelling, you can spell the cuboid with the length, width and height of 4 decimeters, 1 decimeter and 1 decimeter respectively, with the surface area of 4 × 1 × 4 + 1 × 1 × 2 = 18 (square decimeter); you can also spell the cuboid with the length, width and height of 2 decimeters, 1 decimeter and 2 decimeter respectively, with the surface area of 2 × 1 × 4 + 2 × 2 = 16 (square decimeter); so the answer is: 18, 16

A cuboid and a cube just make a new cuboid. The surface area of the new cuboid is 12 square centimeters larger than that of the original cuboid,
What is the surface area of a cube?

What is added is the four sides of the square 12 △ 4 = 3
The area of each face of a cube is 3 square centimeters
So the surface area of the cube is 3 × 6 = 18 (square centimeter)

A cube and a cuboid form a new cuboid. The surface area of the new cuboid is increased by 60 square centimeters. What is the surface area of the cuboid

(60/4)*6=90
The surface area of a cube is 90 square centimeters
