Answer:
30
Step-by-step explanation:
We require to calculate the volume of 1 brick
V = lbh ( l is length, b is breadth and h is height ), that is
V = 14 × 8 × 5 = 560 cm³
Now divide the volume of concrete available by the volume of 1 brick.
number of bricks made = = 30
We are given
It takes a word processor 22 minutes to word process and spell check 4 pages
so, firstly we can find rate
total time =22 min
number pf pages =4
processing rate = ( number of pages)/( total time)
So, processing rate is
page /min
now, we are given total number of pages =26
Time = (total number of pages)/( processing rate)
so, time is
now, we can simplify it
So, the time taken to word process and spell check 26 pages is 143 min........Answer
