Question

Two cubes 512 cm3 are joined end to end. Eind the surface is 26 m2. Eind the area m of base​

Answer 1

Step-by-step explanation:

Volume of cube = l

Volume of cube = l 3

Volume of cube = l 3

Volume of cube = l 3 l

Volume of cube = l 3 l 3

Volume of cube = l 3 l 3 =512 ⇒l=8

Volume of cube = l 3 l 3 =512 ⇒l=8Hence side is 8 cm

Volume of cube = l 3 l 3 =512 ⇒l=8Hence side is 8 cmwhen we join two cubes, we will get a cuboid whose length is 16cm , h=8 , b=8

Volume of cube = l 3 l 3 =512 ⇒l=8Hence side is 8 cmwhen we join two cubes, we will get a cuboid whose length is 16cm , h=8 , b=8Total surface area of cuboid = 2(lh+bh+lb) = 2(128+128+64) =2(230)= 640cm

Volume of cube = l 3 l 3 =512 ⇒l=8Hence side is 8 cmwhen we join two cubes, we will get a cuboid whose length is 16cm , h=8 , b=8Total surface area of cuboid = 2(lh+bh+lb) = 2(128+128+64) =2(230)= 640cm 2

Volume of cube = l 3 l 3 =512 ⇒l=8Hence side is 8 cmwhen we join two cubes, we will get a cuboid whose length is 16cm , h=8 , b=8Total surface area of cuboid = 2(lh+bh+lb) = 2(128+128+64) =2(230)= 640cm 2

Volume of cube = l 3 l 3 =512 ⇒l=8Hence side is 8 cmwhen we join two cubes, we will get a cuboid whose length is 16cm , h=8 , b=8Total surface area of cuboid = 2(lh+bh+lb) = 2(128+128+64) =2(230)= 640cm 2 Lateral surface area of cuboid = 2h(l+b) = 24x8 (16+8) = 384cm

Volume of cube = l 3 l 3 =512 ⇒l=8Hence side is 8 cmwhen we join two cubes, we will get a cuboid whose length is 16cm , h=8 , b=8Total surface area of cuboid = 2(lh+bh+lb) = 2(128+128+64) =2(230)= 640cm 2 Lateral surface area of cuboid = 2h(l+b) = 24x8 (16+8) = 384cm 2
