The volume formulas of cuboids and cubes are written as? Cuboids and cubes are written as? letter

Volume = L * w * h
v=a*b*c
=S * H (s = bottom area, H = height)

Volume formula of cuboid and cube

Cuboid volume = length × width × height = bottom area × height = cross sectional area × length
Cube volume = edge length × edge length × edge length = bottom area × height

The sum formula of volume, surface area and edge length of cuboid cube

Cuboid volume = length x width x height
Surface area of cuboid = (L x W + L x H + W x H) x2
The sum of cuboid edge length = (L + W + H) X4
Cube volume = edge length x edge length x edge length
Surface area of cube = edge length x edge length x6
Sum of cube edge length = edge length x12

(1) There is a class, 56 students are divided into several groups to plant trees, 152 saplings are divided into each group, at most can be divided into several groups, each group is divided into several saplings?

The problem of finding the greatest common divisor;
56=7*2*2*2
152=2*2*2*19
The greatest common divisor is 2 * 2 * 2 = 8
152÷8=19
Answer: can divide into 8 groups at most, each group divides 19 saplings

There are 56 students in a class. How many groups of trees are planted in the cemetery on average? How many trees can each group get

The greatest common factor of 56 and 152 is (56152) = 8
152 △ 8 = 19 (trees)
A: each group gets 19 trees

Fifty two students of class five (1) went to plant trees outside the school. If each student planted three trees, the whole class could plant more than fifty-two of the seedlings
Five (1) how many trees should each student be worth to plant?

(52 * 3 + 52) * 2 △ 52 = 8 (trees)
A: five (1) students want to plant these trees, with an average of 8 trees per person

A class of 42 students participated in tree planting, with 3 boys and 2 girls on average. It is known that there are 56 more boys than girls. How many boys and girls do you want?

Let X be male and y be female
be
3x-2y=56
x+y=42
How to solve the equation
x=28 y=14
There are 28 boys and 14 girls

There are 42 students in class 3 planting trees. The average man plants 3 trees and the average girl plants 2 trees. There are 56 trees for men and 56 trees for women

x + y = 42
3x - 2y = 56

There are three classes in Grade 6 planting trees. Class 61 planting trees is two fifths of the total. The ratio of class 62 and class 63 planting trees is 2:3. Class 61 planting trees is 2:2
64 more trees are planted. How many trees are planted in three classes of grade 6?
Use arithmetic

Class 2 and class 3 are 3 / 5, and their ratio is 2:3, so class 2 is 3 / 5 * 2 / 5 = 6 / 25
64 ÷ （2/5 -6/25) = 400
A total of 400 trees were planted

There are three classes in Grade 6. Class 1 plants 42 trees, class 2 plants two-thirds of class 1, and class 3 plants five times of class 2
How many trees are planted in class three?

2 classes = 42 × 2 / 3 = 28 trees
3 classes = 28 × 5 / 4 = 35 trees
Comprehensive formula:
42×2/3×5/4
=28×5/4
=35 (trees)
A: Class Three planted 35 trees
