Surface area of box = 94cm²

Step-by-step explanation:

Given that:

Width of box = 3 cm

Length of box = 5 cm

Height of box = 4 cm

Surface Area = 2lw + 2lh + 2hw

Surface area = 2( lw + lh + hw )

Surface area = 2(5*3 + 5*4 + 4*3) = 2(15+20+12)

Surface area = 2(47) = 94 cm²

Hence,

Surface area of box = 94cm²

1. 16.64

a^2+b^2=c^2

pr^2=pq^2+qr^2

pr^2=14^2+ 9^2

pr^2=196+81

pr= sqr root of 277

16.64

2. 11.31

c^2-a^2=b^2

18^2- 14^2=b^2

b^2=324-196

b=sqr root of 126

b=11.31

hope it ! (btw im in connections academy to, good luck! )
