The surface area of a cuboid is 120 square centimeters, which can be divided into two equal cubes. How many square centimeters is the surface area of each cube? Use the equation!

Let the area of each face of a cube be x square centimeter
6Xx2-2X=120
10X=120
X=12
12x6 = 72 square centimeter

There is a cuboid with a square bottom, 18cm in height, and a square after the side is expanded

The length of the bottom side of the cuboid is: 18 △ 4 = 4.5 (CM), the volume is: 4.5 × 4.5 × 18 = 364.5 (cm3); a: the volume of the cuboid is 364.5 cm3

How many cuboids can be divided into at least 24 cm long, 18 cm wide and 12 cm high cuboids of the same size?

This problem is actually the conversion of finding the greatest common divisor
The common divisor of positive integers 24,18,12 is 1,2,3,4,6, and the greatest common divisor is 6
24/6=4,18/6=3 12/6=2
4 * 3 * 2 = 24

The length of three sides of a right triangle is 6cm, 8cm and 10cm respectively. The area of this right triangle is______ ．

A: the area of this triangle is 24 square centimeters. So the answer is: 24 square centimeters

It is known that the circumference of an isosceles triangle is 12cm. Let its waist length be x (CM), then the function of the base length y (CM) with respect to X is______ ．

According to the meaning of the question, we get 2x + y = 12, then y = 12-2x, so the answer is: y = 12-2x

An equilateral triangle has an area of 7.8 square meters and a height of 1.3 meters. What is the perimeter of the equilateral triangle?

Wait for the side? Wait for the waist
The bottom is 12m long and the waist is (root 3769) / 10
The girth is 12 + (root 3769) / 5
What's the height of your equilateral triangle

The area of an equilateral triangle is 108cm2, the height is 18cm, and how many cm is the circumference
The area of an equilateral triangle is 108cm2, the height is 18cm, and how many centimeters is the circumference?
..

108×2＝216
216/18=12
12×3＝36

1: An equilateral triangle has an area of 7.8 square meters and a height of 103 meters?

If the side length is a, then the area is a quarter root sign 3 * a ^ 2 = 7.8. If the side length is 18, the high root can't be 103. If the side length is equal, it should be 15.588

Two similar triangles with an area ratio of 1:9 to know that the perimeter of one triangle is 18cm, and how to calculate the perimeter of the other?

The area ratio is 1:9
The perimeter ratio is 1:3
If the circumference is 18cm, the triangle is large
The perimeter of the other triangle is
18 / 3 = 6 (CM)
If the circumference is 18cm, the triangle is small
The perimeter of the other triangle is
18 * 3 = 54 (CM)

The perimeter of rectangle ABCD is 36cm, e is the midpoint of BC, and ∠ AED = 90 °, then the area of rectangle is CM & # 178;

Obviously, the triangle AED is an isosceles right triangle. If AB is x, then AE is root 2x and ad is 2x. The remaining side length is calculated, and the area of the rectangle is calculated
As for why AED is an isosceles right triangle, it's up to you to analyze it. I won't tell you more. If you understand it, then your geometry will not be a big problem in the future
