Answer:
volume = 8x21x17 = 2856cm³
TSA = 2( 21x17+ 17x8 + 21x8) = 1322cm²
LSA = 2( 21 + 17)× 8 = 608cm²
Step-by-step explanation:
formulas I used
volume of a cuboid = lxbxh
Total surface area = 2( lb+ bh+ lh)
lateral surface area = 2( l+ b)× h

Lateral surface area of a cuboid = 2 × height × (length + breadth)
=2*8(21+17)
=16(38)
=608 sq cm..
Total surface area of a cuboid = 2(lb + bh + hl).
=2(21*17+17*8+8*21)
=2(357+136+168)
=2(661)
=1322 sq cm..
