Question

1. in order to find the density of a solid, you should multiply the length x width x

a) diameter
b) height
c) base
d) circumference

1. weight is measured in

Explanation:

1. For question 15:

• # Explanation:
• ## Step1: Recall density formula
• Density $

ho=\frac{m}{V}$, and for a rectangular - solid, volume $V = l\times w\times h$ (length $\times$ width $\times$ height). To find the volume (a step in finding density), we multiply length $\times$ width $\times$ height.

• # Answer:
• b) height

1. For question 16:

• # Explanation:
• ## Step1: Recall weight units
• Weight is a force and is measured in newtons (in the SI - system). But among common units, weight is often measured in units like grams, kilograms (mass units which are related to weight by $F = mg$ where $F$ is weight, $m$ is mass, and $g$ is the acceleration due to gravity). In the imperial system, it can be measured in pounds. However, if we consider the most basic science - related options, weight is related to mass and the gravitational force acting on it. Mass is often measured in grams or kilograms.
• # Answer:
• (No options provided for question 16, but if we assume common mass - related units for weight in a basic science context like grams or kilograms could be correct answers if they were among the options). If we consider the SI unit of force which is related to weight, the answer could be newtons if it was an option). Since no options are given for 16, we can only solve 15 completely. The answer for 15 is b) height.
