ft.

Answer 1

Given,

Given,length = 4ft

Given,length = 4ftwidth/breadth = 3ft

height = 3ft

now,surface area of cuboid = 2(lb + bh + hl)

after inserting values we got,

→ 2 [(4×3)+(3×3)+(3×4)]

→ 2 ( 12 + 9 + 12 )

→ 2 × 33 = 66 sq unit

therefore , surface area of cuboid is 66 sq.unit

hope this answer helps you dear! take care and have a great day ahead!
