Question

three cubes each of side 4cm are joined together volume side by side to farm a cuboid the surface area of the cubiod is​

Answer 1

Answer:

length of cuboid = 3 × 4 = 12cm

breadth of cuboid = 4cm

height = 4cm

$2(12 \times 4 + 12 \times 4 + 4 \times 4) \\ 2(48 + 48 + 16) \\ 2(112) \\ 224$

Answer 2

Step-by-step explanation:

if we join 3 cube together so it will become cuboid

dimensions of cuboid are

lendth = 12

breadth = 4

height= 4

so total surface are of cubiod = 2( lb + bh + hl )

2(12×4+4×4+4×12)

2(48+16+48)

2×112

224cm^2
