Final answer:
To find the amount of glass needed to build the greenhouse, calculate the volume and surface area of the greenhouse. The volume can be found by multiplying the length, width, and height of the greenhouse. The surface area can be calculated by finding the area of each of the six sides of the greenhouse and adding them together.
Step-by-step explanation:
To find the amount of glass needed to build the greenhouse, we need to calculate the volume and surface area of the greenhouse.
a) Volume of greenhouse space:
To find the volume, we multiply the length, width, and height of the greenhouse. For example, if the greenhouse is 10 m by 15 m by 3.0 m, the volume would be (10 m)(15 m)(3.0 m) = 450 m³.
b) Surface area of the greenhouse:
To find the surface area, we need to calculate the area of each of the six sides of the greenhouse and then add them together. If the greenhouse is rectangular, the surface area would be 2(length × width) + 2(length × height) + 2(width × height). For example, if the greenhouse is 10 m by 15 m by 3.0 m, the surface area would be 2(10 m × 15 m) + 2(10 m × 3.0 m) + 2(15 m × 3.0 m) = 420 m².
c) Thickness of the glass:
To determine the thickness of the glass, you would need to consult the specifications of the glass manufacturer or the designer of the greenhouse.
d) Weight of the glass:
The weight of the glass can be calculated by multiplying the volume of the glass by its density. The density of glass can vary depending on the type of glass used. Once you have the weight, you can determine the amount of glass needed by dividing the weight by the weight per unit area of the glass.
