How many liters is a kilogram

How many liters is a kilogram

The kilogram is a unit of weight
A liter is a unit of volume
It depends on what one kilogram is
Different matter, different density, different volume
If it's water, its density is 1, then it's 1 liter
If it was something else, like oil, it would be more than 1 liter
Volume * density = mass of matter

There are 1 and 3 / 5 cubic meters of wood, and 1 / 4 of them are used. How many cubic meters are used?

1 and 3 / 5 × 1 / 4 = 2 / 5 (cubic meter)

A round wood is 4 meters long and 10 cm in diameter. How many are there in a cubic meter?

10 cm = 0.1 M
1÷（3.14×0.1/2×0.1/2×4）
=1÷0.0314

The general formula of an is an = [n (n + 1) / 2 * (n + 1) (n + 2) / 2] / (n + 1) = 1 / 4N (n + 1) (n + 2) = 1 / 4 (n ^ 3 + 3N ^ 2 + 2n) Sn = 1 / 4 [1 / 4N ^ 2 (n + 1) ^ 2 + 3 * 1 / 6N * (n + 1) (2n + 1) + 2 * n * (n + 1) / 2] = 1 / 4 [1 / 4N ^ 2 (n + 1) ^ 2 + 1 / 2n * (n + 1) (2n + 1) + n * (n + 1)]

It is known that the sum of the first n terms of the arithmetic sequence {an} is SN. If S12 = 21, then A2 + A5 + A8 + a11=______ ．

According to the meaning of the question, S12 = a1 + A122 × 12 = 21, {a1 + A12 = 72, A2 + A5 + A8 + a11 = 72 + 72 = 7

Y = Xe Λ - x, find the derivative or differential of Y '

According to the derivation rule of the product of two functions, f (x) = g (x) * H (x), f '(x) = g' (x) * H (x) + G (x) * H '(x)
So y '= 1 * e ^ (- x) + X * e ^ (- x)'
=e^(-x)+x*(1/e)^x*ln(1/e)
=e^(-x)-x*e^(-x)
=e^(-x)*(1-x)
