Maths homework volumes anyone can help?

Answer 1

Answer:

1) Volume of cuboid =l * b*h

9.7*1.8*2.5=43.65

2a =......

Step-by-step explanation:

look at the diagram .the third is complete and the Instruction says they all have same volume so :2.5 *8*9 = 180.

definitely the volume for each of the cuboid is 180.

Volume of cubiod = l*b*h

a)180 = 4*5*a

180 = 20a

180/20 = 20a/20

a= 9

b) 180 = 6*6 *b

180 = 36b

b= 180/36

b= 5

c) 180= 2.5 *9*c

180 = 22.5 *c

c=180/22.5

c=8

I don't know 3and 4

pls mark me brainlest I need it dearly
