First, let's calculate the volume of the rectangular prism:
Volume of rectangular prism = length x width x height
Volume of rectangular prism = 10 x 5 x 6
Volume of rectangular prism = 300 cubic centimeters
Next, let's calculate the volume of the cylinder:
Volume of cylinder = π x radius^2 x height
Volume of cylinder = 3.14 x 2^2 x 6
Volume of cylinder = 3.14 x 4 x 6
Volume of cylinder = 75.36 cubic centimeters
Now, add the volumes of the rectangular prism and the cylinder to find the total volume of the candle:
Total volume = volume of rectangular prism + volume of cylinder
Total volume = 300 + 75.36
Total volume = 375.36 cubic centimeters
Rounded to the nearest tenth, the volume of the candle that Wangshu designed is 375.4 cubic centimeters.
Therefore, the closest option is A. 476.4 cm3.
