Answer:
the total surface of the box is 486 cm 2
.......
The surface area of the object above can be calculated by summing up all the areas of the surfaces. Therefore, we will have 5 surfaces with rectangles as the shape. The volume would be the product of the length, width and the depth. We calculate as follows:
SA = 2(depth)(length) + 2(depth)(width) + (width)(length)
SA = 324 yd^2
VOlume = 30x10x.3
Volume = 90 yd^3
35.98 - 18.25 = 17.73
The t-shirt cost her 17.73.
