A cuboid wood block, cut from the top of the cuboid 5 cm high, the rest is a cube, the surface area reduced by 120 square centimeters______ Cubic centimeter
The original cuboid's length and width are: 120 △ 4 △ 5, = 30 △ 5, = 6 (CM); the original cuboid's height is: 6 + 5 = 11 (CM); the original cuboid's volume is: 6 × 6 × 11 = 396 (cm3); answer: the original cuboid's volume is 396 cm3. So the answer is: 396
A cuboid, height reduced by 5cm, just become a cube, surface area reduced by 120 square centimeters, find the volume of the original cuboid
What is the perimeter of the base of the cuboid
120 △ 5 = 24 (CM)
What is the length and width of a cuboid
24 △ 4 = 6 (CM)
Cuboid height
6 + 5 = 11 (CM)
What is the volume of a cuboid
6 × 6 × 11 = 396 (cm3)

The bottom () is 4cm, and the height () is cm. When the side is expanded, it is () shape, and the area is () square centimeter. The surface area of this figure is () square centimeter
In the following figure, the bottom () is 4cm and the height () cm. It is a () shape with an area of () square centimeter. The surface area of this figure is () square centimeter, and the volume is () cubic centimeter.
The cylinder is 6cm long and 4cm in diameter
Bottom radius 2cm
The circumference is 2 π r = 12.56
The length of the cylinder is 6cm
It's a rectangle, 12.56 in length and 6.56 in width
The area is 12.56 × 6
The surface area of the figure is 2 base area + rectangle area
25.12 + 12.56 * 6 cm2,
Volume is base area times height
25.12*6
Cubic centimeter
Find the area of combined figure: (unit: cm)
The top of a trapezoid is 8cm, the bottom is 12cm, the area is 40cm, the height is () cm
Urgent 1!
The area of the trapezoid is the sum of the bottom and the top multiplied by the height divided by 2
The height is 40 * 2 / (12 + 8) = 4
