A quantity of identical plastic blocks weighs 10.98kg.If each block weighs 54.9g,how many blocks are there?
A.200 B.100 C.400 D. 500****.I think A is the answer,if not plz correct me.
convert 54.9g to kg
54.9g = 0.0549kg
let y = number of blocks
mass of all the blocks = mass of one block X number of blocks
10.98 = 0.0549y
y = 200 blocks
Y =200
To find the number of blocks, we need to divide the total weight of the blocks by the weight of each individual block.
Given:
Total weight of the blocks = 10.98 kg
Weight of each block = 54.9 g
To convert the weight of each block to kilograms, divide it by 1000:
Weight of each block = 54.9 g ÷ 1000 = 0.0549 kg
Now, divide the total weight of the blocks by the weight of each block to find the number of blocks:
Number of blocks = Total weight of the blocks ÷ Weight of each block
Number of blocks = 10.98 kg ÷ 0.0549 kg
Number of blocks ≈ 200 (rounded)
So the correct answer is A. 200
To find the number of blocks, we need to divide the total weight of the blocks by the weight of each block. Here's how you can calculate it step by step:
1. Convert the weight of each block to kilograms:
54.9g = 54.9 / 1000 kg (since 1 kg = 1000 g)
= 0.0549 kg
2. Divide the total weight of the blocks by the weight of each block:
10.98 kg / 0.0549 kg = 200
Therefore, the correct answer is A. There are 200 identical plastic blocks.
