What is the total material weight of a load consisting of 20 pieces of 4 foot x 10 foot steel sheets that are 1/4 inch thick?

What is the total material weight of a load consisting of 20 pieces of 4 foot x 10 foot steel sheets that are 1/4 inch thick?

• A. 6400 lb
• B. 8160 lb
• C. 9000 lb
• D. 10000 lb

Answer: (B)

To determine the total material weight of the load made up of 20 pieces of steel sheets measuring 4 feet by 10 feet and having a thickness of 1/4 inch, we first need to calculate the volume of one sheet and then find the weight based on the density of steel. 1. **Calculate the volume of one steel sheet**: - The dimensions of a sheet are 4 feet by 10 feet. - Convert the thickness from inches to feet: 1/4 inch = 0.25 inch / 12 = 0.02083 feet. - Volume \( V \) of one sheet = length × width × thickness = \( 4 \, \text{ft} \times 10 \, \text{ft} \times 0.02083 \, \text{ft} \). 2. **Volume calculation**: - Volume of one sheet = \( 4 \times 10 \times 0.02083 = 0.8332 \, \text{cubic feet}\). 3. **Calculate total volume for all sheets**: - Total volume = Volume of one sheet × number of sheets = \( 0.8332 \,

To determine the total material weight of the load made up of 20 pieces of steel sheets measuring 4 feet by 10 feet and having a thickness of 1/4 inch, we first need to calculate the volume of one sheet and then find the weight based on the density of steel.

1. Calculate the volume of one steel sheet:

• The dimensions of a sheet are 4 feet by 10 feet.

• Convert the thickness from inches to feet: 1/4 inch = 0.25 inch / 12 = 0.02083 feet.

• Volume ( V ) of one sheet = length × width × thickness = ( 4 , \text{ft} \times 10 , \text{ft} \times 0.02083 , \text{ft} ).

2. Volume calculation:

• Volume of one sheet = ( 4 \times 10 \times 0.02083 = 0.8332 , \text{cubic feet}).

3. Calculate total volume for all sheets:

• Total volume = Volume of one sheet × number of sheets = ( 0.8332 ,
