Surface area of small box = 2(4×10) + 2(4×14) + 2(10×14)
= 2(40+56+140)
= 472 cm²
Surface area of large box = 2(4×20) + 2(4×14) + 2(20×14)

FIRST OF ALL WE FIND FOR THE AREA OF THE RECTANGLE THEN WE ADD THE RESULT TO THE AREA OF THE TRAPEZIUM.
Step-by-step explanation:
area of a rectangle = L× B= 4×8= 32ft.
Area of a TRAPEZIUM = L×B×H = 4.5×14×4=252ft
(A) RECTANGLE+ (A) TRAPEZIUM= 32ft+252ft
= 284ft.
