有一條數時，佢就要計面積，但冇講單位，如下↓
THE length of a square is 8. find the area of it.
咁我做果時就冇寫單位，如下↓
the area of the square
=8x8
=64
老師就扣我unit 分，咁unit應該寫咩呢?

✔ 最佳答案

當題目沒有一個特定的單位時，你可以用 (unit) 作為單位。例如：
==================================

The length of a wire is 8. What's the length of half of it?

half of the wire
= 8/2
= 4 units.

==================================
The length of a square is 8. find the area of it.
the area of the square
=8x8
=64 square units

==================================

The length of a square is 8. find the volume of it.
the volume of the square
=8x8x8
=512 cubic units
