the width of a box is one third of its length. the height of the box is one third of its width. if the length of the box is 27cm, what is the volume of the box?
a. 81cm³
b. 162cm³
c. 243cm³
d. 729cm³

Respuesta :

Answer:

d) 729cm^3

Step-by-step explanation:

Length =27cm

Width = 1/3 of length

= 1/3 of 27cm = 1/3 × 27cm = 9cm

Height = 1/3 of width

= 1/3 of 9cm = 1/3 × 9cm = 3cm

Thus, length = 27cm; width = 9cm; height = 3cm

Hence, volume = length × width × height

= 27cm × 9cm × 3cm

= 729cm^3

Volume is a three-dimensional scalar quantity. The volume of the box is 729 cm³.

What is volume?

A volume is a scalar number that expresses the amount of three-dimensional space enclosed by a closed surface.

The volume of a room or box that is the shape of a rectangular prism is calculated by multiplying the length, width, and height of the prism.

Volume = Length × Width × Height

Given that length of the box is 27 cm. Also, it is mentioned that the width of a box is one third of its length. Therefore, the width of the box is,

Width of the box = (1/3) × 27cm = 9cm

Further, the height of the box is one third of its width. Therefore, the height of the box is,

Height of the box = (1/3) × 9cm = 3 cm

Furthermore, the volume of the box can be written as,

Volume of the box = Length × Width × Height

                               = 27cm × 9cm × 3cm

                               = 729 cm³

Hence, the volume of the box is 729 cm³.
