Answer:
Total surface area is 1152 cm² and volume is 2048 cm³
Step-by-step explanation:
Since, by stacking 4 cubes of side 8 cm on top of the other,
Then we obtained a cuboid,
Having length, l = 8 cm,
Width, w = 8 cm,
Height, h = 4 × 8 = 32 cm,
Surface area of a cuboid,
A=2(lw+wh+hl)
A=2(8*8+*32+32*8)
=2(64+256+256)
=2(576)
1152 cm²,
=
Volume of the resultant figure,
V = lwh
= 8 × 8 × 32
= 2048 cm³
