I need help please help me and I need the work.

question 1 asks about the volume  and question 2 asks about the surface area.. I can't see all of question 3... soo I'll give  you the first two only

Step-by-step explanation:

this seems like it would be easier to figure out.. if we did the volume of the block that would fit around the odd shape of the foam soooo

the block would be 10 inches tall by 36 inches long by 20 inches in depth

use a calculator.. 10 x 36  x 20 = 7200 is  the volume... of just a block that would fit perfectly over that foam structure.. now subtract the two pieces that are not part of the block.. the long rectangle and the triangle off the end.

the first one to subtract is a block that is 8  x 5 x 20= 800

the second piece to subtract is the triagle block that is 18 x 8  so the formula for the area of a triangle is 1/2 base * height = 1/2 (18*8)= 72

7200-800-72=  is the total volume of the shape

the surface area is just add up each flat area of the shape

side = 36x10 - 8x5 - 1/2(8x20)

side = 240

5x20 + 8x20 + 5x20 + 10x20 + 20x20 + 2x20 +36x20 + 2(side)= 2200

the transverse axis of a hyperbola is the line that contains the two vertices and the two focuses.

in this example (hyperbola of equation x^2/2 - y^2/4 = 1), the transverse axis is the  x-axis  .
