there is a rectangular structure that is 12 feet long, 10 feet wide, and 5 feet high. The floor and 4 walls are all one foot thick. How many blocks are used to make the structure?

Question

It is a cubical structure.

Answer 1

the floor area of the structure is 10 x 12 = 120 sq feet

the two walls will be. 5 x 12 x 2 = 120 sq feet

the other two walls will be  5 x 10 x 2. = 100 sq feet

so the whole area of the structure will be  120 + 120 + 100  =. 340 sq feet

since we use cubical blocks of 1 feet we will need 340 blocks
