Answer:
S.A=792 ft²
Step-by-step explanation:
The surface area of this prism is given by
2wl+2lh+2hw where h is the height,l is the length and w is the width
Given: l=15", w=12" and h=8"
Finding area of rectangle surfaces
A1=2(lxw)=2(15×12)=360 ft²
A2=2(l×h)=2(15×8) =240ft²
A3=2( h×w)=2(8×12) =192ft²
Total surface area
A1 +A2+A3
360+240+192
S.A=792 ft²
