B. 105.5 cm
Step-by-step explanation:
A = 2 (LW + LH + WH)
L (Length) = 6.5 cm
W (Width) = 3.5 cm
H (Height) = 3 cm
A = 2 (LW + LH + WH)
A = 2 ( 6.5 x 3.5 ) + ( 6.5 x 3 ) + ( 3.5 x 3 )
( 6.5 x 3.5 = 22.75 )
( 6.5 x 3 = 19.5 )
( 3.5 x 3 = 10.5 )
A = 2 ( 22.75 + 19.5 + 10.5 )
A = 2 ( 52.75 )
A = 105.5 cm
