Question

Wendy made two rectangular prism jewelry boxes, one small and one large. The dimensions of the large jewelry box are three times

the dimensions of the small jewelry box. If the surface area of the small jewelry box is 103 cm, what is the surface area of the large
jewelry box?
A. 618 cm
B. 927 cm
C.
309 cm
D. 2,781 cm2

Answer 1

309 Cm.

Explanation:

Since the dimensions of the Large Jewelry Box is tripled, and all the sides are only added together, the answer of the question is simply the Surface Area of the Small Jewelry Box x 3.

103 x 3 OR 103 + 103 + 103 = 309.

_______________________________________

100 + 100 + 100 = 300

3 + 3 + 3 = 9

300 + 9 = 309.
