A solid cubiod measures 7cm, 5cm,3cm. (a) Calculate the total surface area of the cubiod. (b) A cube has the same volume as the cubiod. Calculate the length of an edge of this cube

Te total surface area (TSA) of the cuboid is the sum of the area of its 6 faces

if the cuboid has width(w)=7 cm, Height (h)=3cm., length(h)=5cm

A=lw=5*7=35 cm²

A2=hw=3*7=21

A3=lh=5*3=15

TSA=2(lw+hw+lh)

TSA=2(35+21+15)

TSA=2(71)=142cm²

volume of the cubiod=l*w*h

V=lhw

V=7*5*3= 105 cm³

the length of an edge of this cube:

since it is a cube then all sides are equal l=w=h

√105= 10.247 ( rounded to the nearest hundredth)









answer: translate the circles so they share a common center point and dilate circle y by a scale factor of 3.
