Answer:
Surface Area A = 490 cm²
Step-by-step explanation:
Surface area of a prism A = 2(w l +h l + h w)
where l = length
w = width
h = height
l = 7 cm; w = 7 cm ; h = 14 cm
Surface Area = 2 { ( 7 × 7) + ( 14 × 7) + ( 14 × 7)}
A = 2 { 49 + 98 + 98}
A = 2 × 245
A = 490 cm²
37.5% of $80 = $30
Since it is marked up, you add $30 to the current price.
$80 + $30 = $110.
