I’m not extremely good at math but I think you need to make -x-y=1 into y=mx+b form and then solve your new equation!
10^2+8^2-7^2/(2*10*8)
= 115/160 = 0.71875 round off to 0.72
Answer:

The surface area of rectangular solid is 208 square centimeter
The volume of rectangular solid is 192 cubic centimeter
<h3><u>Solution:</u></h3>
Given that rectangular solid has sides of 4 cm, 6 cm, and 8 cm
To find: surface area and volume of rectangular solid
Length = l = 4 cm
Width = w = 6 cm
Height = h = 8 cm
<h3><em><u>
The formula to find the surface area of a rectangular prism is:</u></em></h3>
Surface Area = 2wl + 2lh + 2hw
where w is the width, the l is the length, and the h is the height.

Thus the surface area of rectangular solid is 208 square centimeter
<h3><em><u>
The formula for volume of rectangular solid is:</u></em></h3>


Thus the volume of rectangular solid is 192 cubic centimeter
