Let’s convert 3 kilograms to 3000 grams just to make things easier.

650 * 4 = 2600 grams. This is the total weight of the 4 blocks.

To find the weight of the final block, 3000 - 2600 = 400 grams

Answer:

the fifth block weighs = 3000-2600 = 400 gram

Step-by-step explanation:

five blocks weigh : 3 kg

4 blocks each weighs 650

total of 4 blocks= 650*4=2600 gram

each kg=1000 gram

five blocks: 3*1000=3000 gram.

the fifth block weighs = 3000-2600 = 400 gram
