Answer:
202cm^2
Step-by-step explanation:
total surface area of the cuboid = 2(lb+bh+lh)
= 2(4x9+9x5+4x5)
= 2(36+45+20)
= 2x101
=202cm^2

Surface Area of cuboid = 202 cm^2
______________________________
Explanation-:
Surface Area of cuboid =
SA=2lw+2lh+2hw
SA = Surface Area
l = length
W = width
H= height
____________________________
Given ,
L = length = 4 cm
H = height = 5 cm
W = width or breadth = 9 cm
To find ,
The surface Area of Cuboid -:
Formula -:
SA=2lw+2lh+2hw
2 x (4 x 9) + 2 x (4 x 5) + 2 x (5 x 9)
2 x 36 + 2 x 20 + 2 x 45
72 + 40 + 90
202 cm ^2
