Answer:
Step-by-step explanation:
Volume of a pyramid = 1/3 * Base area * height
If the top of the monument is 11m tall, then the height of the pyramid is 11m. If it will take C of bronze to make the top that is 11 m tall, the volume of the pyramid is 22m³.
Substituting the given data into the formula to get the base area;
[tex]22 = \frac{1}{3}* B * 11\\ 22 = \frac{11B}{3} \\22*3 = 11B\\66 = 11B\\B = 66/11\\B = 6m^{2}[/tex]
Since the base of the pyramid is rectangular in nature,
Base Area = Length * Breadth
Base Area = 6m², and the length of the base is given as 2m, the missing dimension will be the breadth of the rectangle.
6 = 2 * Breadth
Breadth = 6/2
Breadth = 3m
The missing dimension is 3m
