Answer 1

To find the surface area of the rectangular prism, we need to add up the areas of all the sides.

There are two sides that measure 10 cm by 4 cm each, so their combined area is 2 * 10 cm * 4 cm = 80 cm2.

There are two sides that measure 17 cm by 4 cm each, so their combined area is 2 * 17 cm * 4 cm = 136 cm2.

There are two sides that measure 17 cm by 10 cm each, so their combined area is 2 * 17 cm * 10 cm = 340 cm2.

Adding up all the areas, we get:

80 cm2 + 136 cm2 + 340 cm2 = 556 cm2

Therefore, Jerry will need 556 cm2 of wrapping paper to wrap the present.
