Answer:
?
Step-by-step explanation:
A = ½(b1+b2)h
B1 and b2 are the bases
H is height
A is area
Here is the simplified answer to this equation: 5 goes into 8 once, so you would bring the 5 on top and subtract 8, the first number, by 5. The answer is three. Bring down the 3 next to the 8. You now have 33. 5 goes into 33 6 times, which equals 30. Write 30 underneath 33 and bring the 6 to the top next to the 1. Bring down the 3 next to the last 3. You now have 33. 5 goes into 33 (once again) 6 times. Write 6 on top next to the last 6. 33 - 30 = 3. 5 cannot go into 3 since it is larger, so 3/5 you write 3/5 as a decimal next to 166 at the top (3 at the bottom and 5 is the larger number at the divisor spot). The decimal is 0.6. Therefore, your answer should be 166.6. To make sure, multiply 166.6 x 5. Hopefully, you get 833.

Another way of presenting this question is to ask: what is the volume of the prism. Sometimes, you can get tripped up on the terminology and fail to discover what it is the question is really asking. To find the volume of this concave prism, we can divide it into two boxes: top box and bottom box. Imagine slicing a knife through the line where the two "steps" intersect. From there, we can apply the basic formula for a rectangular prism and add up the volumes.
Top Box:
A = height x length x width
A = 10 x 40 x 20
(the height is 10 because it is equal to the tallest height minus the shorter height)
A = 8000 in. cubed
Bottom Box:
A = height x length x width
A = 20 x 60 x 20
A = 24000 in. cubed
Total Volume = 24000 in. cubed + 8000 in. cubed = 32000 in. cubed

Answer:
440cm²
Step-by-step explanation:
*Area= (a+b)/2×h
(19+25)/2*20
= _ * 440cm². *_
