Answer:
Option (4)
Step-by-step explanation:
Volume of a rectangular prism is given by the formula,
Volume = Length × Width × Height
From the picture attached,
Length of the prism = 5 cm
Width of the prism = =
cm
Height of the prism = =
cm
Volume of the given prism = ×
×
=
=
= cm³
Therefore, Option (4) is the correct option.
We need to find the unit price of each box.
So, a box that weighs 30 Oz costs $4.50.
lets say that 30 Oz box is named box 1. We can use unitary method to find out the unit price of box 1.
Unitary method is a process to find the value of a single unit.
Now,
30 Oz costs $4.50
therefore, 1 Oz should cost:
dollars
So, the unit price of box 1 is $0.15.
Now, lets say the 20 Oz box is named box 2. Again we can use unitary method to find out the unit price of box 2.
Now,
20 Oz box costs $3.60
therefore, 1 Oz should cost:
dollars
So, the unit price of box 2 is $0.18.
