Question

Two cubes each of volumes 64 cm are joined chd to end. Find the
om are joined end to end. Find the total surface area of the resulting cubord.​

Answer 1

Answer:

Step-by-step explanation:

volume of cube 1 = a^3 = 64= 4^3

a= 4

h=4

b=4

added end to end then length will be 4+4 = 8 cm

b will be same

h will also be same

so

tsa of the new cuboid is 2(lb+bh+hl)

2(8*4+4*4 +4*8)

2(32+16+32)

2(64+16)

2(80)

160 cm^3
