Answer» Volume of one cube=512 cm³a³=512 cm³a=8 cm Length of resulting cuboid= 16 cmBreadth of resulting cuboid=8 cmHeight of resulting cuboid= 8 cm Surface area of the resulting cuboid=2(lb+bh+hl)=2(168+88+8*16) cm²=2(128+64+128) cm²=2(320) cm²=640 cm²

Answer»

Volume of one cube=512 cm³a³=512 cm³a=8 cm

Length of resulting cuboid= 16 cmBreadth of resulting cuboid=8 cmHeight of resulting cuboid= 8 cm

Surface area of the resulting cuboid=2(lb+bh+hl)=2(16*8+8*8+8*16) cm²=2(128+64+128) cm²=2(320) cm²=640 cm²
