Question

A cubical box has each edge 10 cm and another cuboidal box is 12.5 cm long, 10 cm
wide and 8 cm high.
Which box has the greater lateral surface area and by how much?
Which box has the smaller total surface area and by how much? please answer the question​

Answer 1

Answer:

8cm squared

Step-by-step explanation:

1) TSA of cube=4a2=4⋅102=400cm2

TSA of Cuboid=2(l+b)h=2(12+10)8=352cm2

difference=400-352=48cm2

2)TSA of cube=6a2=6(10)2=600m2

TSA of cuboid=2(lb+bh+hl)=352+2(120)=592m2

difference=600-592=8cm2.
