In general, to find the surface area of a rectangular solid, remember that each face is a rectangle, so its area is the product of its length and its width (see the image below). Find the area of each face that you see and then multiply each area by two to account for the face on the opposite side.
Answers & Comments
Answer:
1.count how many no each of geometrical figures [triangle, rectangle, square, circle, semicircle etc]for whom you know the formula of area.
2.measure the dimensions of each type which is valid to calculate the area.[ side , L andB, Radius etc]
3. calculate the area of each figure and multiply with no of similar figure.
4. find the grand total to get total surface area.
Answer:
VOLUME V=LWH
SURFACE AREA=2LH+SLH+2LW+2WH
