Question

four cubes each of 10 cm edge are joined end to end find the surface area of the resulting cuboid ​

Answer 1

edge of cube = 10 cm

breadth of resulting cuboid = 4× 10 = 40cm

length of resulting cuboid = 10cm

height of resulting cuboid = 10 cm

total surface area of the cuboid = 2(lb+ bh+ hl)

answer :: 2( 10×40 +40×10+ 10×10)

2× (400+400+100)

(2×900)cm2 = 1800 cm2

area of resulting cuboid is 1800cm2

Answer 2

Answer:

$1800 \: cm {?}^{2}$
