Final answer:
To find the total surface area and volume of cubical objects, measure their length, breadth, and height and use the appropriate formulas.
Step-by-step explanation:
To find the total surface area of a cubical object, you need to measure its length, breadth, and height. Let's suppose the lengths of the two cubical objects in your room are 10 inches, 12 inches, and 15 inches, and 8 feet, 9 feet, and 10 feet. To calculate the total surface area, you can use the formula: Total Surface Area = 2(length × breadth + breadth × height + height × length). Substitute the measurements into the formula to find the surface area in different units. To find the volume, you can use the formula: Volume = length × breadth × height. Substitute the measurements into the formula to find the volume in different units.
