What is the volume of a box with width 4cm, length 2m and height 50mm
please show work

4,000 cm^3

Step-by-step explanation:

Let's make all of the dimensions cm:

1 mm = .1 cm

(divide the mm by 10 to get the value in cm)

50 mm = 5 cm

The height is 5 cm.

1 m = 100 cm

(multiply the m by 100 to get the value in cm)

2 m = 200 cm

The length is 200 cm.

Now, let's use the formula for the volume of a rectangular prism.

V = lwh

V = 200(4)(5)

V = 800(5)

V = 4,000

The volume of the prism is 4,000 cm^3 or 4,000 cubic centimeters.

3x3 = 9 and 2x2 = 4

step-by-step explanation:

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
