The bottom area of a cube is 25 square meters, so its surface area is () square meters, and its volume is () cubic meters
150 125
The edge length of a cube is three fourths of a meter. How many square meters is its surface area and how many cubic meters is its volume
3 / 4 decimeter = 0.75 decimeter
1. Surface area: 0.75 × 0.75 △ 100 × 6 = 0.03375 (M2)
2. Volume: 0.75 × 0.75 × 0.75 △ 100 = 0.000421875 (M3)
The surface area of a cube box is 72dm2, and the floor area of this box is 72dm2______ dm2．
72 △ 6 = 12 (square decimeter). A: the floor area of this wooden box is 12 square decimeters
A rectangle with a circumference of 64 cm is made up of three identical small squares. What is the circumference of each small square? (hint: draw a picture)
As shown in the figure: the side length of the square is 64 △ 2 △ 3 + 1, = 64 △ 2 △ 4, = 8 (CM); the perimeter of the square is 8 × 4 = 32 (CM). Answer: the perimeter of each small square is 32 cm
How many centimeters is the circumference of a rectangle made up of two squares with a circumference of 4cm?
6
Use four small squares with side length of 1cm to make a big square. (as shown in the picture) the perimeter of this square is______ Cm
(1 × 2) × 4 = 8 (CM); answer: the perimeter of this square is 8 cm; so the answer is: 8
Use 4 small squares with side length of 4cm to form a rectangle. What's the circumference of the rectangle
It's my honor to answer this question for you
First of all, you need to determine how to spell it. According to the meaning of the title, you can only spell four words side by side. Then, width remains the same, or 4, length 94 4 × 4 = 16 16 × 2 = 32, then 32 plus two width 32 + 4 × 2 = 40
OK !
The perimeter of a square is equal to that of a rectangle 20 cm long and 12 cm wide. How many centimeters is the side length of the square?
The solution is (20 + 12) × 2 / 4, = 64 / 4, = 16 (CM); a: the side length of this square is 16 cm
