H is 10 ft tall, 10 ft wide, thickness of block will be 2.5 ft?

Question

• The sixth grade class at Hernandez School is building a giant wooden H for their school. The H will be 10 feet tall and 10 feet wide and the thickness of the block letter will be 2.5 feet.

• How large will the H be if measured in square feet?
• The truck that will be used to bring the wood from the lumber yard to the school can only hold a piece of wood that is 60 inches by 60 inches. What pieces of wood (how many pieces and what dimensions) are needed to complete the project?

 

 

Answer 1

One side of the H is 10' x 2.5 ft = 25 sq ft. Other side of H is the same = 25 sq ft.

H is total 10 ft wide, minus the 2.5 ft, minus 2.5 ft makes the H "bar" 5 ft long by 2.5 ft. wide = 12.5 sq ft.

12.5 + 25 + 25 = 62.5 sq ft. (takes a lot of plywood) 3-- 4 ft x 8 ft sheets of plywood.

Might want to consider 8 ft high x 8 ft wide using 2 ft thick block letters. Comes out looking about the same ratio, and would only take 2 sheets of plywood. Generally can legally haul 8 ft wide preassembleld " H" on a truck, but not 10 ft wide "H".
