Monroe is gift wrapping a box that has the shape of a right rectangle or prism the box has a length of 20 cm a width of 7 cm and a height of 15 cm how many square is centimeters giftwrap will monroe need to cover the entire outside of the box

All faces are rectangles.
Each two opposite faces are congruent and have the same area.

Two faces measure 20 cm by 7 cm.
Two faces measure 20 cm by 15 cm.
Two faces measure 15 cm by 7 cm.

total surface area = 2 * 20 cm * 7 cm + 2 * 20 cm * 15 cm + 2 * 15 cm * 7 cm

total surface area = 280 cm^2 + 600 cm^2 + 210 cm^2

total surface area = 1090 cm^2

W-14=t. that i think is the answer idk
