Answer:
260 cm²
Explanation:
Bottom surface area = 5 x 10 = 50
Surface area of the 2 long sides = 2(10 x 7) = 140
Surface area of the 2 short sides = 2(5 x 7) = 70
Total surface area = bottom + 4 sides = 50 + 140 + 70 = 260 cm²
310cm
The Total surface of cuboid is S=2(lb+bh+lh)
l=length
b=breadth b means w (width)
h=height
S=2(50+70+35)
S=2(155)
=310cm
