Question

A = 20см в = 19см с = 5см Р=? S=? V=?

Answer 1

Ответ:

Ну если это куб то чтоб объем найти нужно все умножить 20*19*5=1900*4=7 600 ну я не знаю покрайне мери я так решаю пириметр 20+19+5=54*4=216

Площадь 20*19*5=1900

Answer 2

To calculate the perimeter (P), surface area (S), and volume (V) of a rectangular prism, we need to know the lengths of its three sides. In this case, you've provided the values for side lengths A, B, and C, so we can use those to find the required measurements.

Given: A = 20 cm B = 19 cm C = 5 cm

To calculate the perimeter (P) of a rectangular prism, you need to sum the lengths of all the edges. In this case, the edges of the prism are equal to the side lengths. Therefore, the perimeter is given by: P = 2(A + B + C)

Plugging in the values: P = 2(20 cm + 19 cm + 5 cm) P = 2(44 cm) P = 88 cm

So, the perimeter of the rectangular prism is 88 cm.

To calculate the surface area (S) of a rectangular prism, you need to find the areas of all six faces and sum them up. The formula for the surface area of a rectangular prism is: S = 2(AB + AC + BC)

Plugging in the values: S = 2(20 cm * 19 cm + 20 cm * 5 cm + 19 cm * 5 cm) S = 2(380 cm² + 100 cm² + 95 cm²) S = 2(575 cm²) S = 1150 cm²

So, the surface area of the rectangular prism is 1150 cm².

To calculate the volume (V) of a rectangular prism, you need to multiply the lengths of all three sides. The formula for the volume of a rectangular prism is: V = A * B * C

Plugging in the values: V = 20 cm * 19 cm * 5 cm V = 1900 cm³

So, the volume of the rectangular prism is 1900 cm³.
