b. 15 m²
c. 2 m²
1.14) the _ an object is, the greater its volume.
a. bigger
b. smaller
c. heavier
1.15) the base unit for volume in the metric system is the _
a. gram
b. meter
c. liter
1.16) which of these can be used to calculate the volume of a rectangular
a. mass/volume
b. length × width × height
c. length × width
1.17) a _ can be used to measure the volume of irregularly shaped objects
a. thermometer
b. spring scale
c. graduated cylinder

Explanation:

1.13

Step1: Recall the formula for the area of a rectangle

The area formula for a rectangle is \(A = length\times width\).

Step2: Substitute the given values

Given \(length = 5m\) and \(width=3m\), then \(A = 5\times3\).

Step3: Calculate the result

\(5\times3 = 15\)

Volume is a measure of the space an object occupies. Generally, the bigger an object is (in terms of the space it takes up in three - dimensions), the greater its volume. Heavier refers to mass, and smaller would mean less volume.

In the metric system, gram is a unit of mass, meter is a unit of length, and liter is a unit of volume.

Answer:

B. \(15m^{2}\)
