Answer:
cuboid has total surface area of the `40\ m^2` and its lateral surface area is `26\ m^2` . Find the area of its base.
Answer:
total surface area of cuboid =2(lb+bh+lh)
2(lb+bh+hl)=4048 cm2
lateral surface area of cuboid =2(hl×hb)
2(hl×hb)=253 cm
2(lb+bh+lh)=4048 cm2
2lb +2bh+2hl=4048 cm2
2lb+2(hl+hb)=4048cm2
2lb+253=4048 cm2
2lb=3795
lb= 1897.5
