Find the surface area and the volume of the cement block in

Find the surface area and the volume of the cement block in the figure shown.

Solution

Area of the rectangular is (A)=length ×width

Length (l)=23in. And width (w)=8 in.

Area (A)=23×8=184 square incheso

Volume of the rectangular is(V)= length × width × height.

Therefore height (h)=6 in.

Volume (V)=3 (l×w×h)

From above diagram l=5 in. , w=4 in. ,h=6 in.

3 is the 3 boxes are there in diagram

Therefore V=3 (5×4×6)

V=3 (120)

V=360 cube inches.
