Final answer:
The volume of the rectangular box with a length of 90 cm, width of 50 cm, and height of 1 meter is 0.45 cubic meters.
Step-by-step explanation:
To find the volume of a rectangular box, we need to multiply its length, width, and height.
In this case, the length is 90 cm, the width is 50 cm, and the height is 1 meter.
However, we need to convert the height from meters to centimeters since the length and width are given in centimeters. So, 1 meter is equal to 100 centimeters.
Therefore, the volume of the rectangular box is:
Volume = length × width × height
Volume = 90 cm × 50 cm × 100 cm
Volume = 450,000 cm³
However, the question asks for the volume in cubic meters.
To convert cubic centimeters to cubic meters, we divide the volume by 1,000,000 (since 1 cubic meter is equal to 1,000,000 cubic centimeters).
So, the volume of the rectangular box is 0.45 cubic meters.
