Answer» GIVEN : A solid cuboid of 15cm X 12cm X 10cm. From each of its vertex cube of edge 2 CM is cut out. To Find : % change in its TSA. Solution: TSA of cuboid = 2 (15 x 12 + 12X 10 + 15 x 10) = 2( 180 + 120 + 150) = 2(450 ) = 900 There will be no change in TSA as cuboid is solid so SURFACE will be there even after cutting cube of 2 cm at different level ( depth) Hence TSA will remain Same % change in its TSA. = 0 % LEARN More: The surface area of a cuboid is 112 cm2. Its length is twice its ... Total surface area of a box of cuboid shape is 500 sq. unit. Its ... |
