Step-by-step explanation:
cuboid
length= 5 cm
breadth = 5 cm
height = 5 + 5+ 5 = 15 cm
total surface area of cuboid
= 2( lb +bh + hl)
= 2( 5*5 + 5*15 + 15*5 )
=2 ( 25 + 75 + 75 )
= 2 * 175
= 350 sq cm

Answer:
Given
side of cube = 5cm
Step-by-step explanation:
Surface area of one cube = 6xside square
=6×5×5
=150cm square
Surface area of three cube= 150×3=450cm square
But the are pasted side by side so 2 of the square will hide 25cm square area so area of resultant figure will be
450-50=400cm square
So area of new cuboid will be 400cm square
