Step-by-step explanation:
Volume of cuboid = lbh
= 22 x 12 x 7.5
= 1980 cm³
Lsa of cuboid = 2h(l+b)
2x7.5(22+12)
=510cm²
Tsa of cuboid = 2(lh+ bh + lb)
= 2(22x7.5 + 12x7.5 + 22x12)
=2(165 + 90 + 264)
= 2(519)
= 1038cm²
For next question you can put the values in the formulas and can find the value.
