Question

A cube in Emily's closet where she stores her jewelry has a side length of 1 1/4 feet.

Answer 1

Answer: $1\dfrac{61}{64}\text{ cubic feet}$

Step-by-step explanation:

Given : The side length of cube = $1\dfrac{1}{4}\text{ feet}$

We know that the volume of a cube is given by :-

$\text{Volume}=(\text{side})^3$

Thus, the volume of the given cube is given by :-

$\text{Volume}=(1\dfrac{1}{4})^3\\\\\Rightarrow\ \text{Volume}=(\dfrac{5}{4})^3\\\\\Rightarrow\ \text{Volume}=\dfrac{5^3}{4^3}\\\\\Rightarrow\ \text{Volume}=\dfrac{125}{64}=1\dfrac{61}{64}\text{ cubic feet}$

Hence, the volume of the cube is $1\dfrac{61}{64}\text{ cubic feet}$

Answer 2

Answer:

1.95 cubic feet

Step-by-step explanation:

We are given that Emily stores her jewelry in a cube and the cube has a side length of $1\frac{1}{4}$ feet.

$1\frac{1}{4}$ feet in an decimal form is 1.25 feet.

We know that,

volume of a cube = s$^{3}$

where s is the side length of the cube.

So substituting this value of side length of cube in the formula to get:

Volume of cube = $(1.25)^3$ = 1.95 feet
