Question

a metallic cuboid of dimensions 100 cm × 80 cm × 64cm is melt and recast into a cube find the surface area of the cube.​

Answer 1

length of cuboid = 100 cm

breadth of cuboid = 80 cm

height of cuboid = 64 cm

ÀTQ

volume of cuboid = volume of cube

l×b×h = a^3

64×100×80= a^3

3√512000= a

217.46= a

surface area of cube = 6a^2

6(217.47)^2

283.733 Cm ^2

Answer 2

Answer:

T S A of cuboid = TSA of cube

surface ara of cuboid =2(lb+bh+lh)

2.100.80+80.64+100.64

is 39040

cube =39040cmsq s a
