Question

The volume and surface area

Answer 1

Volume of cylinder is 402.1238....=402.12ft
Volume of rectangle is 1344ft
Add both together= 1746.12ft

Surface area of rectangle:
Length=14ft
width= 8ft
height =12ft

14x12=168x2=336
8x12=96x2=192
14x8=112x2=224
336+192+224=752

Surface Area of cylinder:

Radius= 4ft
height=8ft
2π r h+2π r^2
2π4(12)+2π4^2
2π48+2π16
301.59+100.53=402.42ft

Add both surface area together=1154.12ft
