top and bottom margins are 7/8 inch there are 5 rows of pictures with 3/16 inch between the vertical what would be the height of each picture

depends on the page size. If the page height is x, the usable height is x-2(7/8) = x - 7/4

In 5 rows there are 4 3/16 spaces. So, the pictures occupy

x - 7/4 - 4(3/16) = x - 5/2 inches.
Divide that by 5 to get the picture height

To determine the height of each picture, we need to subtract the margins and spacing from the total available height.

Let's start by calculating the total vertical space we have for the pictures. We have top and bottom margins of 7/8 inch each. Since there are two margins (top and bottom), the total margin space is 2 * (7/8) = 14/8 inch.

Next, we need to account for the spacing between the pictures. There are 5 rows of pictures, so there will be 5-1 = 4 gaps between the rows. Each gap has a width of 3/16 inch. Therefore, the total spacing between the rows is 4 * (3/16) = 12/16 inch.

Now, we can calculate the available height for the pictures by subtracting the margin and spacing from the total height. Assuming the total height is given, we can subtract the margin space (14/8 inch) and spacing (12/16 inch) from the total height to get the available height.

Finally, to find the height of each picture, we divide the available height by the number of rows. This will give us the height of each row, and since all rows have the same height, it will also be the height of each picture.

Here's the calculation:
Available height = Total height - (Margin space + Spacing)
Height of each picture = Available height / Number of rows

Please provide the total height, and I can calculate the height of each picture for you.
