Answer Key
Storage units: KB, MB, GB, TB
Section A: Quick Questions
Q1
A — 1 GB is bigger than 1 MB
Q2
B — About 1000 MB
Q3
A — KB, MB, GB, TB
Q4
B — A short text document
Q5
A — About 4 GB
Section B: Match the Pairs
Q1
1 MB → About 1000 KB. A small photo or a short song clip is often a few MB.
Q2
1 TB → About 1000 GB. A big storage unit for a whole library of games and videos.
Q3
Each storage unit is about 1000 times bigger than the one before it, so you can convert up the ladder. → 1 GB = 1000 MB
Q4
To check if files fit on a drive, put the file sizes and the drive space in the same unit and compare. → 3 x 2 GB = 6 GB, which is less than 64 GB, so it fits
Q5
1 KB is bigger than 1 MB → The units are in the wrong order. A MB is about 1000 times bigger than a KB, so 1 MB is bigger than 1 KB.
Q6
A 500 MB game fits on a 256 KB drive → 500 MB is far bigger than 256 KB. The units were not compared. 256 KB is only about a quarter of 1 MB, so the game will not fit.
Section C: Definitions
Q1
KB, MB, GB, TB — Units of storage size built on the byte. Each unit is about 1000 times bigger than the one before: 1 KB, then 1 MB, then 1 GB, then 1 TB. Use them to check if files fit on a drive.Section D: Fill in the Blanks

5 MB x 200 photos = 1000 MB
1000 MB = 1 GBSection E: Spot the Error
Q1
C — Each unit is about 1000 times the one before it. A GB is 1000 MB, not 1000 KB. The line should be 1 GB = 1000 MB.
Q2
C — Going from GB to MB gives a bigger number, so you multiply by 1000. Dividing is wrong. It should be drive_GB * 1000.
Q3
A — A kilobyte is about 1000 bytes, not 100. The line should be 1 KB = 1000 bytes.
Q4
B — A 2 GB drive holds 2 * 1000 = 2000 MB. Multiplying by 100 gives the wrong size. It should be 2 * 1000.
Q5
B — A GB is smaller than a TB. 1 GB is about 1000 MB, so the line should be 1 GB = 1000 MB.
