A cube has a base area and perimeter of 9 square decimeters. What is the surface area and volume of the cube

A cube has a base area of 9 square decimeters. What is the surface area and volume of the cube
9=3×3
The length of the cube is 3 decimeters
Surface area 9 × 6 = 54 square decimeters
Volume 3 × 3 × 3 = 27 cubic decimeter

The circumference of a cube is 8 cm, and its surface area is 20 cm. Find its volume
The question is so strange, please answer it quickly

The side length of the bottom surface is 8 △ 4 = 2cm
high
（20-2x2x2）÷8
=12÷8
=1.5 cm
volume
2x1.5 = 6 cc

Use a number of 16 cm long and 12 cm wide rectangles to form a square. How many cm is the minimum side length? At least several pieces of rectangular paper

The least common multiple of 16 and 12 is 48
So the minimum side length of a square is 48CM,
At least rectangular paper is needed
（48÷16）×（48÷12）
=3×4
=12 (sheet)
