just base everything off tens and go from there
There are 3 shorter boards because if you divide 27 by 9 it equals 3.
So find the volume of the separate shapes. For rectangular prisms (which includes cubes), multiply width by height by length. So multiply 4 by 6 by 2. And for the cube, multiply 2 by 2 by 2. Then, to find the total volume, add the two together.
Answer:
search khan academy and theres video about it, for some reason brainly wont let me put answers and the explanation.
Step-by-step explanation:
Answer: Either 28in or 26in
A table cloth 40 inches squared could be 1 by 40, 2 by 20, 4 by 10, 5 by 8
1 by 40 would have a perimeter of 1(2) + 40(2) = 82in
2 by 20 would have a perimeter of 2(2) + 20(2) = 44in
4 by 10 would have a perimeter of 4(2) + 10(2) = 28in
5 by 8 would have a perimeter of 5(2) + 8(2) = 26in
1 by 40, and 2 by 20 are highly unlikely table cloths so it is either 26in or 28in
