Question

A=5дм b=19см h=4см V=?

Answer 1

а = 5 дм = 50 см - длина

b = 19 см - ширина

h = 4 см - высота

V - ?

- - - - - - - - - - - - - - - - - - -

S = a · b = 50 · 19 = 950 см² - площадь основания

V = S · h = 950 · 4 = 3800 см³ - объём

1 дм³ = 100 см³

Ответ: 38 дм³.

Answer 2

To find the volume (V) of a rectangular prism (also known as a rectangular cuboid), you can use the formula:

V = l * w * h

Where:

• l is the length
• w is the width
• h is the height

In your case, you have:

• Length (l) = 5 dm (decimeters)
• Width (w) = 19 cm (centimeters)
• Height (h) = 4 cm (centimeters)

Before you calculate the volume, you need to ensure that all the measurements are in the same unit. Since 1 dm = 10 cm, you can convert the length from decimeters to centimeters:

Length (l) = 5 dm * 10 cm/dm = 50 cm

Now, you have all measurements in centimeters, so you can calculate the volume:

V = l * w * h V = 50 cm * 19 cm * 4 cm V = 9,500 cm³

So, the volume (V) of the rectangular prism is 9,500 cubic centimeters or 9,500 cm³.
