Answer:
4066+2/3
Step-by-step explanation:
So to find the surface area of the bottom box it will be :
2((20+40)x15+20x40)=3400
For the Half cylinder on to it will be:
10x10xpiex40x1/6= 2000/3pie
12981 to the nearest thousand
2 is in the the thousands place
to the right of 2 is 9 and it is higher than 5
that means 2 becomes a 3 and the hundreds, tens and ones are zeros
13,000
