Maria wanted to bring back 5 million grains of sand from her trip to the beach. Each grain of sand weighs approximately 6.7×10^−7 kg. How heavy is the bag of sand that Maria brings home?(1 point) Responses
To find the weight of the bag of sand, we need to multiply the number of grains by the weight of each grain.
Number of grains: 5,000,000
Weight of each grain: 6.7×10^−7 kg
Weight of the bag of sand = (5,000,000) * (6.7×10^−7) kg
Multiplying these values, we get:
Weight of the bag of sand ≈ 3.35 kg
So, the bag of sand that Maria brings home weighs approximately 3.35 kg.
