Question

1. (l64) find the area of the square.

a) 1.5² or 2.05 square centimeters
b) 1.5² or 2.15 square centimeters
c) 1.5² or 2.25 square centimeters
d) 1.5² or 2.5 square centimeters
e) 3 square centimeters

1. (l64) find the volume of the cube.

a) 3y cubic meters
b) 3 cubic meters
c) y³ cubic meters
d) $\frac{y^{3}}{3}$ cubic meters
e) $\frac{1}{3}$ cubic meter

Explanation:

Step1: Recall area formula for square

The area formula for a square is $A = s^2$, where $s$ is the side - length of the square.

Step2: Substitute side - length value

Given $s = 1.5$ cm, then $A=(1.5)^2= 2.25$ square centimeters.

Step3: Recall volume formula for cube

The volume formula for a cube is $V = s^3$, where $s$ is the side - length of the cube.

Step4: Substitute side - length value

Given $s = y$ meters, then $V = y^3$ cubic meters.

Answer:

1. c) $1.5^2$ or 2.25 square centimeters
2. c) $y^3$ cubic meters
