bill is replacing the grass in his yard with cement .the yard is 300m long and 100m wide. if cement is 15cents per cm how much would it cost?
He's replacing the grass with concrete, not cement.
300 m = 3,000 cm
100 m = 1,000 cm
3,000 * 1,000 = 3,000,000 square cm
3,000,000 * 0.15 = $__________
3000000*0.15= $450000
To calculate the cost of replacing the grass with cement, we need to determine the area of the yard and then convert it to centimeters since the price of cement is given per centimeter.
Step 1: Calculate the area of the yard.
Since the yard is rectangular, we can use the formula: Area = Length × Width.
Area = 300m × 100m = 30,000 square meters.
Step 2: Convert square meters to square centimeters.
Since 1 meter = 100 centimeters, we need to multiply the area by 10,000 (100 × 100) to convert square meters to square centimeters.
Area in square centimeters = 30,000 square meters × 10,000 = 300,000,000 square centimeters.
Step 3: Calculate the cost of the cement.
The cost of cement is given as 15 cents per centimeter.
Cost = Area in square centimeters × Price per centimeter.
Cost = 300,000,000 square centimeters × $0.15 = $45,000,000.
Therefore, it would cost $45,000,000 to replace the grass in Bill's yard with cement.
