Which of the following terms can be used when referring to the heaviness of an object? Height, length, area, weight, or capacity.

The five different possible answers that we’re given are all things we can measure. We can measure height, length, area, weight, or capacity. And the question asks us which of the terms can be used when referring or when talking about the heaviness of an object, how heavy something is. Perhaps you know what the answer is already. But let’s just go through each of the five words and remind ourselves what they all mean.

Our first measurement word is “height.” We use the word “height” to describe how tall something is. We might use a ruler to measure height. Our second measurement word is “length.” The word “length” is used to describe how long something is. And again, this is a bit like height. We’d use a ruler to measure length. Our third measurement word is “area.” The word “area” describes the space inside a shape.

None of these words so far refer to the heaviness of an object. What about our next word, “weight”? We would use the word “weight” to describe how heavy an object is or how much that object weighs. So we found the correct answer.

Let’s just go over what the word “capacity” means. The capacity of an object is the amount that that object can hold. We usually talk about capacity when we’re talking about liquid, for example, the amount of fizzy pop that a cup can hold.

So in this problem, we were given five measurement words: height, length, area, weight, and capacity. We’ve been through each word and thought about what each one means. The word that we’d use when referring to the heaviness of an object is “weight.”
