RECTANGULAR PRISMS (CUBOIDS)
So the volume of the cuboid (left) is 10cm X 5cm X 4cm = 200 cubic cm
Its surface area is 2ab = 100   +    2bc = 40    + 2ac =80
      Total surface area 100 + 40 +80 =220 square cm

LIST OF SHIVA CHARITY SCHOOLS
SHIVA Charity (UK) puts these free educational pages on its web site in order to be used primarily in Nepal, and Sri  Lanka, where lessons are mostly repetitive "chalk and talk" and curriculum restrained. We are involved in teachers' resources training there, and hope that schools in the UK and elsewhere will support SHIVA Charity's cause with funding. Please visit our main pages to see the work we do, and how we raise money for individual projects and for child sponsorship.
