Question

only 2 question, the first one I did but second one I'm not able to do​

Answer 1

If u observe carefully , you may see that there are 4 cuboids of same volume , so calculate volume of one and multiply by 4.

volume =15*5*5 = 15*25 = 375 cm^3

volume of prism = 4*375 = 1500 ^3

hope it helps you

Answer 2

Answer:

Step-by-step explanation:

cubiod                           small cubiod

L = 15 cm                         l =1 5 cm

B = 15 cm                         b = 5cm

H = 5 cm                          h = 5 cm

Volume   =  L x B X H   +  l x b x h

               = 15 x15 x5  + 15 x 5 x5

              =  1125   + 375

             = 1500 cm³
