Answer:
D 286in^2
Step-by-step explanation:
We want to find the surface area
7*9*2=126
9*5*2=90
5*7*2=70
70+90+126=286
Answer:
D ) 286 inch^2
answe
Step-by-step explanation:
this box is having two flat surface, that are rectangular in shape, so area of these two surfaces = length x breadth
=( 9 x 7)2= 126 inch^2
now area of two side surfaces = length x breadth
= (7 x 5)2 = 70 sq inches
now area of two front and back surfaces = length x breadth
= (9 x 5)2=90 square inches
because this box is cuboidal in shape, hence add the area of all six surfaces= 126+70+90= 286 square inches
Hence it proved , she will need total 286 square inches wrapping paper to wrap this box
