A cube has a surface area of 96 square decimeters and a volume of 1______ Cubic decimeter
The area of each side of a cube is: 96 △ 6 = 16 (square decimeter). Because the square of 4 is 16, the edge length of the cube is 4 decimeters, 4 × 4 × 4 = 64 (cubic decimeter). A: the volume is 64 cubic decimeters. And the answer is: 64
1000 square = 100 * 100 * 100... Guess an idiom
The left side is the square of a thousand, and the right side is three hundred multiplication. That is to say, the square of a thousand is calculated by the multiplication of a hundred, so the answer is "do everything possible."
What is the idiom of 1000 * 1000 = 100 * 100 * 100?
A: on the left is the square of a thousand, and on the right are three hundred multiplication. That is to say, the square of a thousand is calculated by the multiplication of a hundred, so we can guess the idiom "do everything possible"
