The sum of the edges of a cuboid is 256 cm, the length is four times the width, and the height is three times the width. Find the surface area and volume of the cuboid
Qoq9645, hello:
Sum of length, width and height:256÷4=64(cm)
Width of box:64÷(4+3+1)=8(cm)
Box length:8×4=32(cm)
Height of cuboid:8×3=24(cm)
Square body surface area:2×(32×8+32×24+24×8)=2432(square cm)
The cuboid volume is:32×8×24=6144(cubic centimeter)
Three cubes with 1 dec decimetre long, are assembled into a cuboid with a volume of () decimetre and a surface area of () cm2. Three cubes with 1 decimetre edges are combined into a cuboid with a volume of () decimetre and a surface area of () cm2.
